Just curious how it compares to 1095, S30V, etc:

Blade retention
Ease of resharpening
Rust resistence
 
for me I am not a fan of 154CM,AUS8 or VG10 but that just me alot of good companies use 154 & VG10 I just don't like 'em
 
Absolutely a great steel. My BassPro 110 in CPM154 takes an extremely fine edge, and is very easy to sharpen on DMT diamond hones -- easier than S30V or VG-10. Very rust resistant (possibly due to the titanium/aluminum/nitride coating). I can't tell the difference in edge-holding between CPM-154, S30V and VG-10 in daily use. Several makers, including Mike Stewart at Bark River -- and there's no one I know who does a better heat treat -- consider it a very tough steel.
 
I personally love 154cm. Good on rust resistance, decent edge holding and pretty easy to resharpen.

If Jeff asked me what steel to use for the stainless Izula coming out next week......err.....:D I'd pick 154cm over s30v and the other supersteels.
 
Not a fan of it overall. I have a Benchmade Griptillian in 154.

Scary sharp from the factory. For me, it dulled rather quickly. I can't seem to get a good edge on it to save my soul no matter what sharpening method I've tried. It could be me though, I'm no expert. No rust issues at all though. Unlikely you'd have any for the most part with 154.

1095 though is my personal favorite. No issues sharpening it at all. Extremely easy. It can rust easily, but I've yet to have it ever be an issue.
 
Remember guys, he's asking about CPM 154 not 154 cm. These are two different steels. I have experience with both and like both, but from my experience CPM 154 takes a better edge and retains it a good deal longer than 154 cm. I think that CPM 154 is an excellent steel. :thumbup:

Same steel, just made in a slightly different (ie gimmicky) way.

I've personally seen no difference in use.

You are correct in that they have the same chemical composition, but there is nothing gimmicky about powdered steel. Crucible uses this technology for a reason. It evenly distributes and refines the carbides in the steel which is very important to getting a nice fine and polished edge that won't damage (ie dull) as easily. There is a legitimate science to metallurgy. You not understanding it (or not wanting to) doesn't make it gimmicky. As I said before I can notice a distinct difference between the two steels in the folders I own. Of course the heat treatment makes a huge difference in how the steels perform as well.

No need to get testy. I worked in a machine shop for over a decade working with all kinds of steels. I fully understand the differences in processes.

In my personal experience with the two steels, which is fairly extensive, I've seen little to no difference in rust resistance (which there shouldn't be), edge retention or edge gaining capability.

YMMV.
 
I have a custom boning knife in cpm 154, i love it, Great edge retention and very rust resistant.

I apologize Shotty. I didn't mean to come across that way and I should have chosen my words better. I'm just not a person who buys into gimmicks, so it kind of rubbed me the wrong way when you stated that the process was just that, a gimmick. Oh well, I guess we all have different knives and our own unique experiences and opinions.

Perhaps "gimmicky" was a poor choice of words on my part. I realize that the powdering and sintering process makes for a more consistant, quality steel but I personally don't feel that it's really needed in a general use tool steel.

Its all about cost vs. Benefit for me. Then again, your talking to a guy who's favorite blades are made from leafspring steel. :D

No hard feelings.
