Recently a soldier on active duty sent me three knives to do work on for him. One was a very high dollar absolutely beautiful custom Greg Lightfoot Catchdog folder for me to see if I could add one of my custom low rider pocket clips to it. The other was an Emerson CQC10 sent to me to convert to one of my massive .160 thick frame locks, which I finished and you can see in my homepage link to my picture galleries in my profile (STRprojects) or on my own forum here on BF's and the third was unmarked, had one little insignia on the blade and although the owner told me in his original email contact what he was sending I knew in advance I had not heard of that last one and upon looking it over could not remember what he called it. I noted there were no marking or ID of the company on the knife other than the little emblem on the blade of a compass. Anyway, it was to eval to see if I could come up with a custom low rider pocket clip for it also.

Ok I admit, seeing the quality of the other two knives this same guy sent me may have played on my judgement a little but then again it was really the knife that I was judging based on what I saw in my hand and based on years of experience working on them. Keep in mind I didn't know the knife and really don't care that much for the Karambit which is what the knife I could not identify was. The Karambit pictured with the hawk bill or claw blade is the one I had sent to me.

I just knew this Karambit was probably between $125 and $200 to look at it. It was solid, it was good looking, and overall the fit and finish, workmanship and every detail of the knife was right up there with many of the other high dollar knives I've handled. In short the knife was flawless. Needless to say when I asked the owner what he paid for it and to tell me again what it was and he told me it was like $28 and some change I about fell over! I believe I wrote him back saying you have to be kidding right? You meant $128 and some change correct? Nope. He got it right the first time. I had to check this out further.

I did some searching and ordered one of each style of Karambit from Knifecenter, and the T5 folder listed on the company web page as BG42 blade steel was ordered direct from the owner himself. I was suspicious of this knife and the listing of the blade steel, particularly when I noticed that some dealers list the T5 as 420HC, while others say its got a blade of 420J and the company making the knife lists it as BG42. In my mind I was thinking there is no way this little knife can possibly be BG42 for $28. For what its worth though, some dealers list this at $46 and shipping.

For me the knife was so inexpensive shipped from Mantis I had to ask, how could it be BG42 blade steel? Well, I asked both on the phone and in writing about this to the company. I have the email from Jared West, director of Mantis knives and the designer of the T5. Jared informed me that the blade steel on the T5 is BG42 blade steel and further, its a folder of his own design that he is very proud of. In our conversation I learned that the T-5 design itself was inspired by an open wheeled KART race car. The original intention for the red ellipse at the opposite side of the handle is for a karabiner. I must admit that even after this conversation via email I still doubted. Nevertheless I don't want to call the man a liar. He says its BG42. I'll take his word for it.

I have not had these long enough to get real in depth on them as far as cutting performance. I have however had them long enough to make a brief commentary.

For the money these knives cost it is my opinion that they are functionally as good or better than many knives 5 times the cost. I gotta tell you, they don't look bad either. The simple fact that the knife of the three sent me that impressed me and stood out the most was the Mantis Karambit has me a bit puzzled because I've been told by competitors to Mantis that its made in China. However, its not stamped made in China and has no other marks on it other than the company trademark logo. I have no proof its a Chinese product here in my hands. The knife stood on its own merit in my hand. Due to the design of the blade and the fact that I am just not that familar with Karambits I can't really say I am the one to test this one though. I'll leave Karambit testing to someone more qualified.

Lets just talk about the build of the knives. The locks on these knives are flawless. No sticking locks here at all, no blade play, just pure function plain and simple. On everyone of them the locks are 420J stainless steel with a black finish. At least I think that is what it is. Some sites list the frames as 420HC steel. It is safe to say that these are not titanium knives but thicker stainless ones on par with some of the newer Kershaw beefcake folders. The blades are perfectly balanced, centered, smooth as silk with no grainy or gritty feeling when opening and closing them and evenly ground. In whittling hardwood just enough to test my own T5 it sliced and cut into it as well as any other knife I've tested NIB with the exception of Spydercos but again, I only did like five or so big slices.

The T5 has no pocket clip but what a great little folder it is for $28 and some change. At 3.1 ounces its an easy carry knife also. I won't use the Karambits. I just had to have them to compare to the one sent to me because I wanted to sample the products for myself to compare them for consistancy. In fact they are out in the mail to a few in my circle of friends to examine for themselves as I type because they impressed me so much. The Karambits are 420 HC blade steel but for what you pay, who cares right? I do note they have a few, well, not really sharp edges, lets just say they are not beveled quite as well as I'd like but to be perfectly honest about that and to throw some perspective on it for you, I've seen this in $200 Emersons I've bought also. I mean if I had a nickel for every time I've taken a NIB knife to the shop to take off some sharp edges I'd have enough for my new grinder.

Anyway, my point is I have some knives to add to the list of inexpensive alternative folding knives to look at if you are in the market and they are here in the form of these Mantis knives. Just something to list side by side with the Byrd folders, the Kershaw Vapor, Storm and other Wal Mart selections we have all deemed worthy if you are looking for a good inexpensive beater or tool box knife. I rate these knives as something you won't much care if you lose or get taken from you or beat up, or just something new and different to check out what these guys over at Mantis are doing. I have three of their knives. I have currently handled four. EDIT: Correction. I now own four since the owner of the Karambit I first saw gave it to me as his gift for the work I did. They are nice. I mean they are really really nice for the money. Could they be better. Sure, I wish there were some additions and some subtractions, but that is par for the course with any knife.

Now do I have any issues at all with them? Ok, if I want to search what can I find? I see a different blade stop set up in the Karambits. The stop pin looks small. Looks built into the blade too because it pivots with the blade when it moves. I note its also on one side of the blade only.

The blade is rock solid when closed and open though. No amount of force moves the pin. The lock doesn't move in further when you really lean into the blade opened either and believe me I've leaned into it on my work table with all 210 pounds of me so its apparently not giving much if at all. In short. I note the stop differences but can't find fault with it. It appears to work fine.

The blades were not as sharp as I like my knives to be but they were certainly better than some others I've paid a lot more money for. About four swipes on a 1200grit Edge Pro ceramic fixed that on each one though and brought the edges up to a quick and easy biting sharp edge.

You need special tools to take them apart. This is like torture to a guy like me let me tell you because I'd love to get inside this Karambit and find out more about that blade stop. :D

If this quality of workmanship, fit and finish and quality blade steel keeps up, it is going to be very hard for the knife buying public to ignore Mantis. I understand 11 new models are being introduced at the Blade Show. Check them out. Add to my thread or start new ones. Trust me. I think we'll want to know more about this new company.

I like the red accent on the frame. how does one produce a bg42 blade at $26?? I think I might like to check it out myself too....where/who sells them?
 
Knifecenter sells them. I got mine from the company just as cheap though.

STR
 
How could BG42 be sent to china ( can it by law?) , made and transported back for the price? Remember Sal talking about BG42 being 1.5 times the price of S30V with over a year lead time.

If you say it's built well then I certainly believe it is, but I'm still having trouble with the BG42 thing. If it's this easy why aren't the other manufacturers doing it too? Heat treating with BG42 is pretty important also, and not the easiest to do correctly.

I'm interested in seeing what kind of long term edge holding and resharpening luck you have with this knife. The company has also advertised using ZDP in knives. If so, they should be made in Japan, not china.

Perhaps I'm cynical but when something seems too good to be true I start getting more suspicous than normal. Joe
 
I'm the same way. At this point I have no reason to distrust the owners word though. The knives have unconditional coverage for the warranty. I know what you are saying though.

I can think of an example with customs. Kevin Wilkins makes knives in Berlin Germany and he uses BG42 a lot also. So apparently some BG42 is getting out of the country to other parts of the world. With contacts in the states anything is possible I guess. Jared seemed to indicate there were not that many of the BG42 ones so I don't know what to tell you if you are curious. Call or write him. He was very quick to respond to me. For all I know the company is producing both. Maybe the BG42 ones have to be ordered direct from Jared. I really can't say.

I know I've shipped things to Australia and to other places in the world as favors for friends when a business wouldn't so perhaps others do also. I've read of that with some Cold Steel knives and others over the years also though.

So long as there is room to give benefit of the doubt I don't see why we can't do that personally. But I understand your point Joe.

This morning I did some brief cutting comparisons using the Mantis T5 folder cutting side by side with my Ray Kirk 52100 custom Scagel reproduction folder.

If any of you are familar with Ray Kirk's 52100 you know that its award winning steel forged by him being a Master Smith and known for its edge keeping with several wins in cutting contests under his belt using blades from this steel.

In cutting 50 slices of 1/2" hemp rope I have some initial reports.

First though, I sharpened each knife using the Edge Pro 120 grit, taking the blades to a 15 degree bevel. Then finished them up using the 220 grit followed by strops on a cardboard legal pad backing and followed after that by 600 grit ceramic and followed by that with a 1200 grit ceramic, followed by 6 strops each on my FlexCut leather strop. Each knife popped hairs off above the arm before the test and sliced thin Postal reciepts with ease before the test.

I first used the Mantis. Initially it sliced cleanly and easily. It took off and sailed through the first 10 slices. Then over the next ten it became steadily harder requiring more sawing motion as I went. The next ten were even harder requiring more force. Then for the rest of the cutting all the way to 50 slices it was progressively harder. By the time I reached the 50th slice it required quite a bit of sawing motion to get the end of the hemp to cut off all the way. Good thing I had gloves on there toward the end. The blade no longer sliced the Postal reciept cleanly at all but could be stabbed into it and made to slice it that way. Hair popping? Forget it. Didn't have a chance. The edge showed some signs of light refelction but no worse than other blades I've tested. For a small knife I found the Mantis to be on par with others I've used. Hemp is very abrasive on the best steels and for smaller more delicate blades even more so. I thought at the end it performed quite well.

I moved on to the Kirk custom. Ray's knife sailed throught the first 20 slices with relative ease. It was not requiring near the sawing motion or the force to cut the hemp after 25 slices. It started dragging a bit more noticed to me and requiring a bit more saw action around 37 slices and up to 50 it too was taking a bit more effort to cut off the ends cleanly. It did better than the Mantis. It cut the Postal reciept but not cleanly. Stabbing it through it sliced better also and for hair popping. It still took off a couple but it took skin too.

Both knives stood up well, both showed little signs under the scope of light reflections from edge dings but not too bad. Both came right back up to a razor sharp biting edge with little work also and are ready to go again.

I'd give the edge here to Ray's custom but in truth that was expected anyway. At least by me. Both knives weight 3.1 ounces and both are about the same size as far as blade length, width and length and thickness of the handles.

Thats all I have to report for now on it.

Even very cheap knives have usually stamped blade material and place of origin.

The fact this one has none of above AND it's advertised as BG-42 IMHO doesn't smell good.

Or, in other words, I don't believe it is BG-42.


(BTW, STR, if you are willing to try something: do you have any 60+HRC knife at hand? It should be possible to scratch glass with it (while it shouldn't be possible with blade that is several points lower). And if I'm not mistaken, properly heat treated BG-42 should be close to 60HRC or above. This may give some clue?)
 
Thats fine with me my friend. I have no dog in the fight and I'm not trying to convince anyone one way or the other. I was just saying I believe in giving the benefit of the doubt. I've spoken with many in the industry about dealing with China. Its very possible that much is lost in the translation many times in dealing with the lanquage barrier between our two cultures but its equally possible that these knives are not China made at all and no one seems to have thought of that.

Getting back to the China thing though, I remember when the 8Cr13MoV blade steel first started showing up in the Byrd line from Spyderco and the first ones were all stamped 440C. Later that was discovered to be not quite true though and corrections were made by Sal promptly to fix that err. My point is if say a knife company is talking to the manufacturers in China and says he wants BG42 blade steel that they may respond with yes we have it and it is Ho Hung 42 (I just made that steel up as an example after a previous dicussion) or something else even close with the number 42 in it because they are lost in the translation barrier between cultures, isn't it feesible that everyone left the conversation thinking they were on the same page at the end where the US owner thought he made it clear about BG42, the China makers think they got it right with ho hung 42 and maybe it went something like, ya, ho hung 42 how many you want? With the rest being history? :D

I really don't know. I do however believe in giving any new aquaintances the benefit of the doubt. Just looking at the knives and letting them do the talking they come off as pretty good quality workmanship for the $. I can't tell you one way or the other as to what the blade steel is or where it is made other than what is put out there by the company. The add on the company web site and the director of the company, Jered West both say the T5 blade steel is BG42.

I do agree that I'm just as puzzled as anyone about the sterile blades and no country of origin markings if they are China made though. You guys are right to question. The Dark Ops thing has all of us a bit on guard and thats good.

Huugh thats a good point on the Rockwell. I'll go one better and just find out what the RockWell hardness is on two of my three Mantis knives, one being the T5 and will publish it when I know. Thanks.

STR
 
Very impressive work from both knives. Thanks for the review, STR! Thanks even moreso for the pictures of the Kirk/Scagel with ironwood.
 
Yeah about that Kirk 52100. You know I found out he lives here in Oklahoma not too far from me. I wrote him and called yesterday in fact and the reason was to see if he'd be interested in making a couple of blades for me Thom. Guess why?

STR
 
Out of curiousity more so than anything else I just tried the hemp rope cutting thing using the Tanto Karambit which just got back to me in the mail. Both the hawkbill blades are still out to others to eval for me. I can safely say that whatever the blade steel is in the T5 it is obvioulsy different somehow than what is in the Karambit. I quit after 20 cuts in the rope, 10 of which were quite painful. This blade is thin too, and chisel grind so it should cut like most Emersons do in the hemp which is quite well even in push cuts. It doesn't do that though and it is in fact requiring far too much force for me to do much more with it. My thumb hurts now. :grumpy:

Because you blush like a newlywed when you see those snakeskin scales? Because 52100 and slipjoint design go together like good beer and better friends? Because you have a generic drop point blank ground out of 52100 and some wild ideas? Because you have the blank reground, tapped, and milled to replace your JYD II's blade and you want a performance-over-hype smith to heat-treat it for you? Because Ray sure seems like good people and you want an excuse to hang out with him?

Why, Steve?
 
All good guesses. For a blade for you is the answer. I know you like 52100 when its done right and remembered you asking me if I knew anyone that could work with it and heat treat it correctly. I didn't know until I found out about Ray that I had someone that could not only do it up right but that was so close I could almost reach out and touch him over in Talequah Oklahoma which is just a short hop from here. I'm hoping to hook up with him one day if he'll grant me an audience.

Huugh.

Since knives I let friends handle came back to me today I have mailed out the T5 and one of my two hawkbil Karambits to a friend to RockWell test for me. I'm going to go out on a bit of a limb here and guess on the T5. After using it I'd be surprised if it Rc's out at 62. My guess is it will hover more like 58-59 Rc based on the edge performance and others in that range I've used. Its probably off but it is my feelings right now that is where it is at. It may be 60 but I'm going with my first guess.

I'll know sometime next week on the two and will post the results.

Hi STR,
I don't doubt you and your friend are familiar with following but for the others: apart from using C scale (which is obvious) Rockwell testing requires that surface of the material which is tested has to be perpendicular to measuring device. This is not exactly easy to do with ground blade and even small inaccuracy can affect the results in significant way.

However I'm curious about the results and I'm looking forward to hearing from you again :thumbup:
