Questions for those who use Talonite knives

Something interesting I have noticed.

My talonite knife seems to cut flesh better than my steel knives.

I bought some sumer sausage and my Talonite blade sails right through, but steel knives, even freshly shapened ones, do not as wel, after they pass through you look at the edge and there are bits of white stuff from the sausage collected on the edge.

Interesting.

i think thats cause the molecules are really large (carbide molecules are huge compared with some of the fine tool steel ones) and so you get a microscopic saw edge. no doubt someone will come on here and tell me i am wrong, but thats what i think, i also think that it works better to sharpen the stuff with a coarser belt vs a finer one, like i do with 440v, 420v, 440c, ats, etc.

OK Tom, you asked for it....YOUR WRONG

Only kidding, I understand what you are saying. We see S.E.M. pics all the time of various tooling, materials and coatings. It would love to see one of a Talonite edge!
I find and you may agree, Talonite slips and slides around more during grinding. Traditional blade steels take a "set" to the wheel and will stay put while grinding. The Talonite feels like there are tiny ball bearings between the material and the belt. Do you experience this phenomenon??

Frantium, the edge rolls easily because the strength is relatively low compared to high end steels. Strength is generally strongly correlated to RC but the relationship is not trivial. As a macroscopic effect of this due to a stab into pine (1 cm penetration) and a slow pull to the side (didn't break the wood out) I got a perm. bend of about 10 degrees in the tip which extended back 5 mm.

Marion are you slicing or pushing the blade during the cuts? What kind of finish are you taking the edge too? Do you know how Allen is doing it?

Tom, if you took a Talonite and 420V blade to a very high polish do the edges act differently?

Frantium :

Looks like prying is a big no-no for Talonite knives.

Since on the Talonite main page a piece of unground stock about 3/16" is bent by hand without a bar, I would not want to do much prying with a blade. However there are people selling dive knives out of Stellite, Kit Carson for example :

I don't know however how much prying strength is necessary on a dive knife. Personally I would want it to be able to take full strength of a one arm pull. I would be curious to know what an actual diver's opinion would be. In any case, the thick stock, sabre grind and broad tips combine to give a strong profile in Kit's blade. I think Mike Turber has one of those from Walt. Hopefully he will do some prying with it and comment on it.

I had to check. mostly because i thought it was a 1/16" bar, but it was .161x.710, or about 5/32 x a little less than 3/4...which is a pretty small chuck of metal. not trying to start any kind of an arguement here, but i would imagine a lot of the tool steels we use would have to be thicker and wider than that to pass a similar test. dont think it said how long it was...but the farther out there the more leverage. I know Talonite has its limitations, but i remember a break test on an extremely thinly ground 154cm knife back in the eighties, and the bottom line was: you would be a smoldering hunk of dead flesh by the time your knife broke.

It was also unground stock. When I first noticed that it seemed to indicate low strength to me. When I saw the list of material properties this opinion was reinforced. After working with the blade for a few weeks I have seen the low strength exhibit itself in all aspects of knife work.

Um, yeah. I broke more than half an inch (>13mm) off the point of a 154CM knife throwing it, and I would not describe that blade as extremely thinly ground; it was flat ground from 1/8" (3.175mm) stock with very little distal taper. I, too, don't seem to bear much resemblance to a smoldering hunk of dead flesh ... last time I looked in a mirror, anyway....

One of the worst failures I have ever seen was a friend using a Benchmade Ascent to remove a broken key from a lock. He inserted the blade carefully and got the tip under the key. He then lifted it out and heard a light click as he was doing this - the tip of the Ascent breaking off. Yes it was a small break, but the stress was the weight of half a key.

mass production knife-mass production heat treat. I am not saying knives dont break, I am saying Talonite is not going to break by looking at it. So far on all the treads I have read about talonite, the only failure i have read about is a knife that was extremely thinly ground giving out at the edge. other than that i am unaware of any talonite knife breaking. right or wrong??

I have seen my Talonite blade take much more extensive damage than two similar profiled VG-10 and ATS-34 blades under the same stress. I also put a perm. bend in the tip of the Talonite blade with some very light prying in a piece of pine. It would require no great effort to break it. The material properties do not lie, the strength is low compared to most blade steels and I have seen this in just about any aspect of performance I have examined.

Tom, based on the way the edge has deformed under stress, I would say it would bend significantly before it fractured. I have not been able to get the material properties for Talonite though. It would be interesting to see how ductile it is compared to say ATS-34.
