Whats so special about M4?

Practical Use said:
I read these posts and I wonder: for most any use that most of us have, does it really make any difference.

I have knives in M2, D2, S30V, VG-10, and etc. etc. - they all cut the things that I need to cut.

I realize that for people with special use needs it can make a difference, but for most of us..........

I can only say that for me ZDP189 does make difference - it cuts more things without failing then other steels. I can use it way longer then other and this is really helpful and useful and way less effort to restore, because it has less damage and it is easy to sharpen. And I use it for everything - from cutting splinter out of my fingers, to whittling aluminum corners.

Now I am spoiled and just can not really use "easy-to-get-unusable" steels. As well as I am looking for something even better - like CPM M4 etc.

Thanks, Vassili.
 
I was a little bit disappointed with BM M2 knives performace compared to harder carbon steel blades on carving hard wood,bamboo,and rattan.I guess it was due to their thicker edges and hardness.Now BM heattreats M4 to HRC60~62,the same as M2,but M4 is much tougher than M2.I wish BM could heattreat them harder.

But I still want a M4 Ares.
 
Now that CPM M4 is a reality I'd like to post other, non crucible comparisons of Carbon/alloy non stainless steels for 3 attributes. The company is a commercial industrial knife/blade manufacturer /sharpener that holds steel from many manufacturers.

I won't hotlink.

wear resistance+ both regular and red hardness http://www.florida-knife.com/wear.html

corrosion resistance= http://www.florida-knife.com/corrosn.html

edge strength/toughness both regular and red= http://www.florida-knife.com/edgestr.html

basic rundown of their non stainless steels :http://www.florida-knife.com/material.html

BTW, I have the Osborne in CPM M4 now. I'll say without reservations it's not going to have the pure wear resistance of CPM S90V. Not as many of those huge, "devil worshipping" vanadium carbides. It sharpens easier. No thinning of the edge has been done yet, or any kind of testing. It is a well built, good knife. If I wasn't getting a M4 710 I'd buy another even though I'm not even the biggest benchmade fan on the boards. I think the edges come too thick, and obtuse, but that's preference on my part, and not a flaw on benchmades part.

I do reccomend one or the other if you can swing it. I'm looking foreward to the 710. Perhaps a Krien regrind can really sort it out.

One last thing. I'm an old Vascowear fan. I've loved it for years. Look at the steel in comparison to some of the newer, more expensive super steels. It confirms what I've been saying for years. Thanks, Joe
