I just compared a Ritter S30V fixed, Ritter M2 Grip, Benchmade H20 and japanese blue/white folder. I'm testing most of them with the stock grind and sharpening. With the exception of the M2 Grip and the H20, these knives have'nt been used yet. The M2 Grip has served as EDC a couple times opening letters and boxes. The H20 was used as a dive knife during a recent trip and was only used to open food packaging and cut paper for the most part before. Due to this I gave them both 2 swipes on a BC loaded strop. At this point all the knives would pushcut paper.

My test was to use each knife to collect and prepare wood from a local stand of trees to make a small fire using only matches. This could be a test of my skills and fatigue as much as the knives but lets move on.


Let me just say that all 4 knives excelled at one facet of my not-so-scientific tests.

Benchmade H20- Fixed, thin, half serrated, flat ground blade. Accelled at cutting small branches with its serrated portion and it felt great in the hand. It was difficult shaving large sections of white wood for kindeling in a side grip due to the serrations. It really chewed the wood up pretty bad and I didnt get the kind of kindeling I was looking for. This is actually a very small fixed blade in X15 since its a dive knife. I was very surprised how well this knife worked at everything since its a superstainless steel. 23 matches to get the fire started. The smallest kindeling was not so small and took forever to catch. Lots tinder brush was needed to get the thing going.

Benchmade Ritter fixed blade- Fixed, thin, flat ground blade. By resting the thumb on top of the scale it chopped decently well for a small knife. It was the most comfortable of the bunch. It worked very well in a side grip and made great tinder. I almost didnt order this knife since I'm not the biggest fan of S30V but I do like it. This is the most expensive knife of the bunch. I'm not going to do a cost analysis but it did offer a lot of the accoutrements the others lacked like extra blade length and an extremely comfortable handle. 2 matches to get the fire started.

Benchmade Ritter Griptilian- Axis locked folder with a thin, flat ground blade. The M2 steel slid through the wood noticable easier than either of the other two. It wasnt effortless but it wasnt as laborious as the others. The handle was comfortable but not as much as the fixed blade. The clip and the texturing provided a secure grip but could get to be a pain. Being a folder and shorter than the ritter fixed it didnt chop very well at all. Perhaps it was due to my purchase on the handle since there isnt that much difference between the two but it was less effective. Also due to the full plain edge it didnt cut branches off trees as well. I did a lot of notching and then breaking branches off to get them where I wanted them. 2 matches to get the fire started.

Small japanese brass handled folder- No lock, laminated blade made of either japanese blue or white steel. I'm not sure of which since the description didnt say either one. I saw these back in the "best knife under $20" thread. I found some at Garrett for $15 and bought 2. It looks and acts very much like a straight razor. The lack of lock hasnt been a problem as long as you dont plan on doing any chopping. I had to collect wood by breaking small limbs off trees. It is a pretty rough design despite being laminated. The two knives are very different from each other probably due to being handmade. This knife was not comfortable to work with for a long period but worked EXTREMELY well cutting the wood. I'm going to guess thats partially due to the very rough grinds micro serrations. You can choke up very close to the blade and partially close the knife and get some great tinder, kindeling and fursticks. The only problem was the knifes handle was basically bent brass and was not comfortable for long periods of time. I took a couple breaks and ended up taking the longest time to make a fire with this knife. This was also the cheapest knife in the comparison. 2 matches to start the fire.


From this I've gathered a few things. I should probably rebevel these knives and do this again to have more constant results. I'll go ahead and come up with some conclusions based on the data I collected though.

The ritter fixed would probably do better in a different steel. The M2 knife seemed to cut better despite the fact that it had been used for some time. I have a Cabelas D2 grip on the way and I'll put it through the paces to see if it does better or worse.

I'm going to have to do this again with a knife that has a differential grind. I'll probably do fine polished edges on the tip and near the choil but put a very rough grind in the middle. I've done this before but never for woodworking and never as rough as I plan for this project. This will allow for having a tip for precise work digging into or outlining something and precision work near the choil but large serrations in the middle to chew up material for semi-sawing.

I'll post pics in a minute.
 
Nice work.

Generally this is a geometry issues more so than dependent on the steel type.

Also due to the full plain edge it didnt cut branches off trees as well.

For smaller blades the most effective way is to lean on the branch hard and cut into the point where it has a sharp bend. This will open and the blade will slide through it very easily.

That is interesting, that style of knife is usually highly polished. The kitchen knives are often left rougher.

I'm going to have to do this again with a knife that has a differential grind.

Generally a good idea.

Great info. About the japanese knife, you can see in someone elses pics from this thread how rough the grind is at the edge.

Whats interesting is how different these knives are between the two I bought. The flipper is different, the blade width is different and neither one of them have symetric bevels. I see that they do exactly what they are supposed to, sharpening pencils and cutting other soft media but I'd think they would want to bring the quality up just a tad. I wont complain about a $15 knife of such good steel though. It seems to do almost everything well which I am going to guess is based on the hard, course edge. I think I'm going to give one of them some attention and clean up and the other I'll leave as is.
 
That is a basic shop knife which is likely why the cosmetics are likely of little priority. Interesting though on the edge finish, I would be curious if that is just a cost issue or how such knives are traditionally sharpened in Japan.

For getting the best possible performance for a given blade, this is a very good read.

It costs nothing but your time and effort to optimize the performance of any blade by determining what edge profile is best suited for your own range of cutting tasks.

Comparing different blades - with factory edges - is likely to prove only that some of those blades are delivered with piss-poor edges that are not suited for your own range of cutting tasks for the materials you wish to cut.
 
Could have sworn I posted about this earlier today, but it's not here, so I guess I didn't.

I want to buy one of these japanese knives for a friend of mine for his first knife, because I think he'd appreciate the style. I want to know if they make 3 inch blade or less sizes, and if you can get one with any kind of lock. Also, where to order would be nice.

I'm willing to bet Vasilli would be able to give us some incite here.

I find that on many occasions the factory edge is rounded, chipped, incomplete or inconsistant. Its especially apparent with cheaper knives like the japanese ones above and the glock field knife. Honestly I could'nt care less since it gives me a chance to play with edge geometry right off the bat and see how easily the steel takes an edge. It also seems that most factory edges are set at whats easiest for the guy working the grinder and not what the knife needs. Spyderco has been the only one consistantly set at least near the ideal geometry, in my experience.

These are described as a 3" blade on the Garrett Wade website where I bought mine.

This small folding knife is both a pleasure to use and to look at. It has a very solid 3" long, 1/8" thick blade mounted in a handsome character-embossed Solid Brass Holder. No spring is used. Folded, it is only 4-1/4" long, opening to 7" overall. Use it for marking out, trimming and everywhere you would use a tough knife. It's equally at home in the workshop or on the desktop. We really like it as something very special

That being said, between the two that I bought, they are dissimilar on every measurement outside of the brass handle. The length and width are visably different but I havent thrown a caliper on them to check the thickness.

This is the only iteration I've seen them in aside from the brass/black handles. Garrett had them on sale last week for 14.99 but it looks like that deal is gone.

While I would agree that only donig such an evaluation would be less than ideal, ignoring the factory performance does eliminate an aspect which is very critical for some people. Very few people will reprofile as not even a large majority of people actually sharpen knives.

Factory edges are fairly important to me. I shouldn't have to remove metal before the knife has been used, and I also feel that somebody making knives should know how to ship them with good edges. That's something that really perplexes me about customs. Sure, some are art pieces and shouldn't cut stuff, but others have no excuse to arrive dull.
 
Indeed, if a knife is dull then everything else can be perfect and it is useless as a cutting tool. A lot of the problem comes from ideas that coarse edges should not shave, large knives should not be "too sharp", etc. . At a minimum you would expect any custom knife to at least match the sharpness common to the inexpensive production Spyderco's.
