Buck 110 Folding Hunter

The Buck website in the FAQ lists 58-61 as the standard hardness range for their blade steels.

Does anybody know what the hardness rating is on these knives?

I have heard is is 55RC.

Send me a target knife and I will have the engineers test it. Dimples will be left on the blade from testing. I'll return the knife after the test and post results.
 
A lot depends on which steel your talking about . As Buck does many high end steels for their 110 . Something like this could be close (by memory) ; 420HC= 57, 425M=58-59, 440C= 58-59rc (Narfang verified this), ATS-34= 60, 154CPM= 61-62, S30V=58 and theres a slew of others I don't recall . BG-42, 154CM, ect.. Does anybody have a 110 with D2 ? DM
 
S30V
This is the absolute best blade steel available and its made in America. S30V contains carbon as well as high amounts of chromium, molybdenum and vanadium. Double-tempered – it can be hardened to a Rockwell hardness of RC 59.5-61.

BG-42 Steel
An extremely high-performance, bearing grade, martensitic stainless steel with significantly more carbon and molybdenum plus vanadium for improved edge retention and strength – it can be hardened to Rockwell hardness of Rc 61-62.

ATS-34 Steel
A very high carbon, chromium martensitic stainless steel, with additional amounts of carbon and molybdenum that add significant edge-holding properties and corrosion resistance. This steel can be hardened to Rockwell hardness of Rc 60-61.

420HC Steel
This is Buck’s standard blade material because it combines the excellent wear resistance of high carbon alloys with the corrosion resistance of chromium stainless steels. Add our exclusive heat-treat process for superior corrosion resistance and you have excellent tensile strength, hardness and wear resistance. 420HC Steel is a High Carbon (HC) version of standard 420 martensitic stainless steels – they can be can be hardened to a Rockwell hardness of Rc 58.

17-7PH Steel
This steel is excellent for water sports applications. It has high saltwater corrosion resistance and better edge retention than austenitic stainless steel. 17-7PH is defined as a chromium-nickel-aluminum precipitation hardening stainless steel, a process that develops hardness at relatively low temperatures, allowing hardening with very little distortion. It can be hardened to a Rockwell hardness of Rc 54-56.

Has Buck ever produced a 110 with D2? I want one!
 
Sea, I know they did a limited edition 118 with D2 steel and I don't know everything on this model so I was thinking maybe . Wolf, CJ commented on S30V's heat treatment in a post last year and used a number like 58-59 so, thats where I got that . DM

Thanks DM! I have that 118 in D2. It was a great deal thru the web store specials. I haven't ever seen a 110 in D2. That would be one to have if it has ever been made!
 
I have read that buck hardens the 420HC at 58 RC. That is plenty hard, considering I put it head to head against M2 high speed steel and S30 V steel and it hung in there right with them.
 
420hc is a great steel. Spectacular corrosion resistance and very easy to sharpen. As long as you always have some sort of sharpening option your good. Since Buck and others make such a wide range of portable sharpeners-we're golden:thumbup:

You have heard incorrectly.

Buck's stated spec is 57-59 or 58±1 (all Rockwell hardness measurements, when correctly stated are ±1. That is as close as the test gets.)

I have tested 3 Buck 420HC blades. All measured 59 on the machine I used.
 
CJ posted that the S30V is done at 59.5-60. Since Paul Bos told me that is what he targets for his custom orders, too, I believe that number is accurate.

Interesting number for the CPM-154. Were those run under one of Paul Bos' programs?

I am always curious why someone questions the hardness of Bucks. Being curious is cool, but if it determines whether you buy one or not, just remember the warranty.

Newell,,,it has been posted in times past that all Bucks heat treat fall under the Bos criteria.

It was in that same post that CJ said the hardness of CMP-154 . Thanks . DM

humm i had heard a rummer that some one at buck did a few
110 blades of D2 .. as a test... and that they were unmarked ...
this has not been confirmed by any one currently at buck...
it may even be jest a pipe dream...
of some one messing around with the laser
who knows ... be nice to fine one ...
 
Interesting, what is the hardness of CPM-154 that Paul Bos heat treats it too on Buck's knives? It doesn't seem too be that high as it sharpens easily, for a CPM metal. On the other hand it does hold it's edge for a very long time.

Basically correct. Actually, most of these hardness tests aren't done with sufficient rigor and so have larger error bars.

It isn't as easy to do good measurements as most folks believe.

Is your machine a 3-point measurement or single point?
