I am thinking of getting a benchmade LFTi (whenever the hell they come out) in cpm m4 but then I saw a kershaw shallot in cpm s110v and I was wondering which steel is better(in terms of hardness, sharpenability, wear resistance, brittleness, and chipping) corrosion resistance is not really an issue to me.:jerkit::D
 
Both top notch steels for edge holding. I'd try and get more information pertaining to the heat treat, as that can make or break a steel.
 
S90V and S110V are more wear resistant than M4, and of course more corrosion resistant. M4 should beat them out in most every other category.

I don't know. I am just wondering why you keep using the "jerk-it" emoticon?

It's my other hobby.;);)

Yeah Jiggy, you're gonna go blind man, quit :jerkit: so much

So does M4 out perform s90V in edge retention?

Hmmm....my eyes are getting worse......

explains what CPM-M4 is

someone with more experience can elaborate on that while I :jerkit::D

Tungsten doesn't automatically mean higher wear resistance. S90V and S110V have more vanadium carbide and considerably more carbide volume overall than M4, which both equal greater wear resistance. However, greater wear resistance doesn't always equal greater edge retention, depending on the knife, application, method of sharpening, etc.

what about edge retention, if the steels(m4, s90v, zdp189, and s110v) are used in a folder like the LFTi, sharpened on a diamond file, steeled, and stropped on loaded leather with diamond paste?

is m4 even a good steel overall?:confused:

I wonder about that. I own a few knives in it and so far it seems to be doing about as well as M2, which is all I ask.

Personally, I'm for seeing any fine grained non-stainless steels being turned into knives. I generally prefer such.

so you think the bm in m4 is worth it?

I find it interesting that high speed steels became so popular in the knife industry over air hardened steels like D2. What's S110V btw, is it new?

Ultimately carbon steel is better than any stainless, we know this. Rust is easy to avoid if you know how to care for your tools. High hardness, high carbon content steel laminated with softer stainless in the Japanese tradition is the way to go. Thinnest edges, easiest sharpening, amazing edge retention, no chipping. You can't beat it.
