So this is my first review of any kind, and here we go. Im just gonna throw all the pics in at the end. Theres a small story behind this knife in that i actually won it. The knife is called "The Surgeon" and its made my EOS Cases which is known for their minimalist wallets, Ti Key-Bars, Ti Multi-tools and various other Ti things. The owner and designer behind the company John Koerner held a drawing for the first prototype of their 3rd knife and posted a video of the drawing on Instagram. I think he said they had around 700 people who could win. I had my name in the mix because I bought one of his wallets, which I am definitely a fan of. So i get a call and John tells me i won a knife and to check out his instagram page. Not only did i not know i was entered but i didnt have an instagram account or even been on there before. I checked out his page and saw everything people were saying and i started to feel bad because of how much people wanted this knife and how excited they all were. But when i saw the name of the knife I actually felt a little less awkward as its also my job title. EOS' first 2 knives, the Orca and the Squid, flippers, were made in limited editions of around 150 i believe. Both sold out in pre-order and were well liked as best i could tell.

But I get the knife and it comes in a Nanuk-nano case, which was great; easily on par with Medfords pelican cases. I open it up and the quality of the anodizing on the frame is instantly apparent. Its violet with a teal clip, thumb stud and barrel spacer. All very well done. John calls it the "Joker Edition" and its not a color scheme i would of ever picked out for myself but actually looks really good and works. I pick this bad boy up and its heft is noticeable, this aint no dainty little EDC. I dont have any specs from the maker but i measured it at exactly 8.5" overall length, 4.75" closed, with a 3.75" long blade (3.3" cutting edge & 1 7/16" wide). As you can in the picture with the Medford its a beefy blade, i measured it at 3/8" at the base of the blade. I was told its CTS-XHP steel and I wont lie, it was pretty dull. I am as yet to sharpen it as my spyderco sharpmaker is in the mail. Ill come back and add this review after i get a chance to sharpen the blade properly. But when i first deployed the blade i found my two favorite parts of the knife: the oversized teal thumbstud with the 5 holes in it, and the deeply satisfying thud when the blade locks up. The heft just makes for such a great sound. But when I go to close it I noticed the first problem: lock stick. And not like kinda stuck, I mean REALLY stuck, and it did it at least 75% of the time. But i looked up how to deal with it and since I did the pencil trick it hasnt been a problem at all. My guess is the problem lies with the fact that it doesnt have a steel insert on the frame lock. But the lockup is rock solid, it aint going nowhere, as is its detent. This is a very well put together knife. Between the size of the blade and the overall construction I feel like I could cut an aircraft carrier in half with this thing.

After I took care of the atrocious lock stick my only complaints with the Surgeon are in its cosmetic design, nothing to do with function. 2 are IMHO but i believe one could be considered an actual fault. The fault is when its closed. As you can see the back side of the blade sticks out a good 3/8". This was done so it would line up with the back of the frame when opened. I did a simple 15 minute photoshop of what the blade would look like if you trimmed both the blade and the frame. The next thing that caught my eye was the clip. I just dont feel like it lines up well with the rest of the frame. The frame is simple and both sides are parallel, so i feel like the clip should be the same to just keep the same flow. Now this is just IMHO, its a personal preference and Im being picky here for sure. But I trimmed the clip on one of the pics so you can see what it would like if i had it Burger King (my way). My only other issue was also in the looks and its a single line near the spine of the blade. Again, this is something thats IMHO and totally has to do with my personal preferences, but i feel like the lines of the blade should follow the lines of the rest of the knife and all the lines are parallel, heading in one direction and this line just throws off the flow. I know how I sound when Im picking on little shit like this because it does not effect the performance at all but to me this is not a knife just about performance, its also a piece of art and the amazing purple and teal anodizing job, snazzy pivot, oversized and well designed thumbstud truly pushes it in that direction. Oh yea, i didnt mention the pivot: Im a big fan. The detail in it is great. really pops in contrast to how simple the overall look of the knife is.

What else is there? It feels good in hand. It looks very angular but manages to be fairly comfortable with the chamfering around the edges. I feel like it could use some jimping to help with grip as the super smooth titanium can get slick. I couldnt imagine what it'd be like with sweaty hands. There appears to be jimping along the spine of the frame but because the grooves dont extend all the way thru the frame they are actually decorative and in no way functional. There are no hot spots. There is a tiny little spot on the base of the base frame lock that could be a problem if someone really did some seriously heavy duty activities and gripped it a particular way but with regular EDC activities it is fine. This is not an "organically designed" knife and it doesnt just melt in your hand, but its definitely NOT UN-comfortable at all. Just somewhere in between. Oh, as much I was pooping on the design earlier there are 2 things I truly do appreciate about some low-key stuff John did with this. The screws for the pocket clip are completely hidden and the milled out undersides of the frame are freaking gorgeous. I mean you can hardly see them but when you peak in there they look awesome. And with the single teal spacer makes this is a VERY open knife, which I am a big fan of. I think another spacer or two might give a chance to add a little more of the teal anodizing but thats not a criticism, just a thought.

I need to end this by saying I wouldnt trade or sell this knife for anything. As much as I feel like i $h!+ all over it, and I honestly feel bad for saying anything negative about something i got for free, I love this thing. I own a medford praetorian and its much more expensive but I feel like this is the jewel of my collection (albeit a very small, but growing one), and I honestly doubt that will ever change. I mean I won it, cmon, how awesome is that? and the guy who gave it to me is super cool, and its a color id never pick and a style I probably wouldnt buy if i had to spend my own money on, but thats not a knock on the knife, its just a preference thing. Everyone has their own tastes and I know there are a TON of people out there who really want this knife. Its funny that i know who they are because they always say they want it on instagram anytime John posts a pic. Even if this wasnt true I wouldnt care, cause its mine. But like i said, I really do relish having this knife. Its just such a pretty purple ;) thanks John, youre the man. And good work Steve, i know you probably put some time in on this too.

Good first review, man.

Gave the right detail, direct feedback without being overly partial or critical, and a nice flow. I can read it both taking the knife as it is and with an actual viewpoint from a human.

Congrats on the win. It's nice finding things out of one's own niche that's not forced on you. It's like a free orange sports car. Something you might own.. if you weren't you.

I too would love that knife, it is sweet.. I probably wouldn't have bought it though. Colors are wicked. Joker is apt.

thanks man, much appreciated. i think the pictures would be better suited within the paragraphs as it would break up the reading some. felt like i was reading a book at one point, but that might be because i re-read it like 5 times proofing it. also, i wish i had more performance review in there, cause im a real user of my knives, i dont own anything I dont carry and use, but i just got it so i havent really performed anything with it other than playing with it for about 18 hours. Like i said, and like you, i probably wouldnt buy it but that has NOTHING to do with the work on it. Johns craftmanship is seriously amazing, this thing is so well put together. We just have different tastes, theres nothing wrong with that. But the anodizing is the best ive ever seen, such a light touch to it. The only real issues i had with it were the blade and I dont think EOS did the blade. I really dont think he would put a blade on their that sticks out like that. Everything he does is so streamlined and so "perfect" that I just doubt he'd let that go, but when you have someone else do something sometimes you just have to work with what you got. Between the weight and how solidly built it is, i feel like I could use as a freakin hammer and it nothing would budge in any direction.
 
Very well-written review. Nice use of measurements and visual comparison to a known standard (the Praetorian). The anodizing may be a bit over the top, but I tend to admire bright color splashes, and could handle this okay.
Your photos and PhotoShop creative ventures are really outstanding; makes your review so much easier to understand.
The resounding "twack" of the opening blade reminds me so much of several Jim Burke folders that I have owned. No other folder has ever, in my experience, sounded quite like that... You have mentioned pronounced blade stick, and your mention of a lockbar insert, as per a Spyderco Military model, would seem to be the better idea.
The spine thickness of 3/16" is on par with your Praetorian and the Strider (0.190") SMF model. Some overly-optimistic owners seem to talk about cutting car doors in half, and so forth. Certainly, you won't damage the tip by prying with it.
One criticism that you had, concerning the rear end of the closed blade that "juts out"...is quite valid. It reminds me of the design of the original Spyderco PM1, which managed to grab at my hand on occasion. Note, that on the PM2, it was corrected.
The skeletonizing of the actual frame member is quite a feat. This is the first time that I've seen it done on the actual frame. From the standpoint of lightening the finished product, this works very well. The narrowed spine, also presumed for weight reduction, doesn't bother me, although the geometry was not to your liking. Likewise, the design of the clip is okay with me, and I actually prefer the original design.
The closed length seems ideal to my "large" hand size also and the use of a nice effective length of CTS-XHP makes for a fine blade-steel.
Thanks for a very well-written review. I think it's a great heavy-duty folder and you'll likely never come close to wearing it out.

Good first review. I enjoyed reading it.

I agree with you about a possible blade redesign to eliminate the protruding portion of the blade when it's closed. Other than that I think you have yourself a sweet blade there! I think the color combo is pretty cool! Congratulations on winning it!

i didnt know you could get an aftermarket lock bar insert. thanks man, thats actually a huge help. and i didnt think about the blade geometry being to lighten it, totally makes more sense now. and the milled out guts look better in person for sure, the pictures dont do them justice. especially because the anodizing has a teal hue underneath the violet, so you get a tiny hint of green along the edges of the cutouts. im gonna look into the Jim Burke folders you talked about. I was thinking about it and one of the reasons mine is so loud is because of how open the frame is. It acts like an amplifier and i think the geometry from the milling helps push the sound around. I think sound is an under-appreciated aspect of premium knives. the sound of its lock-up, the little click when the blade pops into detent. the "ting" sound you can get from the pocket clip sometimes when its a solid piece of titanium or steel.

i said i wouldnt trade it for anything, but thats a lie. my grail knife, thats the only one. a blacked out microtech anax. thats literally the only blade....and thanks for the kind words man. i cant say i worked on this for a long time, couple hours maybe, but the review meant a lot to me just cause the knife means a lot to me. ive never really been a creative kind of guy outside of landscaping, so this is one of the only outlets of that nature i enjoy. i work with a lot of people that i dont fit in with and since i left school and stopped playing basketball a couple years ago (injuries from motorcycle wreck) ive been trying to find a niche or subculture to enjoy and knives seem like a cool place. lots of good dudes in here.
