Lowest Tolerance Knives

I recently picked up my first couple of Sebbies and what got me was I had the pivot screw out of the knife......and there was absolutely no blade play in any direction. That totally flipped me out!
Pretty tight tolerances!

Same with the Cold Steel 4-MAX. I took the pivot screw out and the blade had no play, nor did it go off center. Also getting the knife apart was a royal pain. I had to pry the knife apart slowly with an eighth inch thick stir stick, then pull the various pins out of the handle with a vise-grip. I also had to squeeze the whole thing back together in my bench vise. The pieces of leather I used to pad both the vise-grip and the bench vise were pretty chewed up as well. Not for the faint of heart or the newb knife tinkerer. :eek: :D
 
Crk, Shiro, Reate Knives to name a few with high tolerances. Spyderco also try and get manufacturers to have high tolerances but probably not to the extent of the above mentioned.

For unique locks and knives in general check out G & G Hawk knives like the deadlock and many other patented locks they've made.

I also came across the Andrei Sanders Provocator, which seemed like a discount Shirogorov with MRBS, but couldn't find any information that justified the price tag.

I have the Provocator. It's not perfect - definitely has some issues - and I'm not sure I'd call it the paragon of precision engineering. But, it's by far my favorite production knife, and I've had (and sold) CRKs and Shiros.

Watch out for Sandrin knives. I would stay away from them until they fix their 30 day warranty policy. They seem like BS artists anyway. "The indescribable Clement noise you can only know and appreciate once you experience"....? Puhleeze.

I originally was very skeptical of Sandrin Knives, but after doing some reasearch I must admit I think they are completely legit.

Link to website:
http://www.turmond.it/

(Let me know if this link violates any terms and I will remove it, I don't think it does since there are no prices mentioned on the page)

The company that created Sandrin Knives is called Turmond, which is a 48 year old TC manufacturing company in Italy. I checked out every page on that site, and they seem legitimate to me. According to Cabot Guns, they manufactured tungsten carbide components for companies such as Rolex (I can't verify this though). All in all, they seem legitimate, and even though their description is a bit fruity, I haven't found a reason not to believe the measurements. I am holding off on it though, because of the price, and because it is a framelock, but still interesting.....

Thanks for all the replies everyone, I am enjoying checking out the recommendations very much.

I have never heard of Sandrin Knives. Their knives look pretty promising to me, might even have to look into one of these for myself. My heart is saying yes, yet my wallet is saying no.
 
I heard that companies that manufacture precise machine parts and such from metal have tolerances of cigar smoke. Pretty insane.
What does that have to do with knives? I don't know but I thought I'd say that.
 
The biggest problem with Sandrin knives is their 30 day warranty for sure. Also how are you going to sharpen tungsten carbide?
 
Ever look at Koenig? Tight tolerances too. Lots of other cnc low production mid techs or customs also. Too many to name off
 
I know some may not like this, but i think benchmade has some very well engineered knives. Their execution in manufacturing can be a different story though. I have always been impressed with benchmade engineering. With spyderco, i have mostly been impressed with their manufacturing and design.
 
I checked my Spyderco Chaparral and mantra just yesterday with a caliper and they were perfect width wise from front to back. Inside the slabs measurements for mantra were really close. Regular Chaparral was absolute perfection on outside. After sharpening both the grinds are nice and even too. Was checking these yesterday because just got me a new sebbie woot.:D respect to taichung factory.

I really like how you can't even push the blade to the side when you put force on it opening it.
 
Try the TAC-FORCE spring assisted opening EMT EMS ORANGE Rescue Folding Pocket Knife. I saw it on amazon for 8 dollars. If it’s good enough for rescue operations the tolerances must be better than aircraft grade. Which Chris Reeves says his knives are

Must be good enough for your profile picture then...

The precision machining displayed in the Tac-Force EMS knife is probably way overkill for a simple knife collector. I mean I doubt most experienced knife makers or even machinists could appreciate the quality that goes into their exacting production.
 
I judge the engineering perfection of a knife when I take it apart and put it back together. If it goes back together and to the same tolerances as before I took it apart and does it easily, I find that impressive. I can not argue with anyone on here who mentioned CRK knives. I have a 13 year old Small Sebenza that still comes apart and goes back together with perfection. The other knife that does meets that level of perfection has been my Hinderer Half Tracks.
 
I'm pretty sure that on any given day, one of these manufacturers will have a CNC that falls out of tolerance specs, just before they do a PM on it. So, anyone with a CNC machine that maintains it 100%, 100% of the time is who you'll probably want to look at. Good luck! :)
