what is the major difference in these steels. Witch one is the best one for price edge-holding finish. I currently use ATS34. thank you

as mentioned above...you are going to be happy with ats, but it is an all purpose steel in my opinion, good for a lot of things but not great for any (except toughness if paul bos is heat treating it but there are tougher steels). there are a bunch of different steels for a bunch of different purposes, and if you ask ten people on this forum, youre going to get ten different answers...you need to read up and decide for yourself.

magnum,

I have made HEAVY DUTY combat knives out of D2. I have Paul Bos heat treat them. They are excellent knives and I would trust MY LIFE with one of these blades.

That is the sound of inevitability.
 
magnum 44 i desagree with you on flexing on d2 take a 12 inch planer blade put it in a vice put a pipe on it and you can bend it 90 degrees an not break it if that isnt flex i dont know what is
 
I use 440-c for most of my stainless knives. I Have Paul Bos treat it. From my hunters feed back it holds an edge better than ats-34. I think cpm440v is better yet. If you are considering d2 try cpm3v instead. It is 4 times tougher than d2 according to Ed Severson of Crucible.
 
Barry, what is the RC of your large combat D2 blades? What are the dimensions of the edge profiles?

maybe i'm wrong guys, i never tested the flexiblity, buy it the chemical composition lead me to believe it wasn't, and a few people told it wasn't. lets put it this way, it's not as flexible as some other steels, like ats-34. i believe 440c to be an all pupose steel also, ats-34 being a better all purpose steel. i'm using bg-42 know, and it's a bear to grind, and takes about twice as much sandpaper to finish.
 
Cliff,

The last combat knife that I made out of D2 was an 8" long, 1/4" thick, 1-1/2" wide spear point double ground blade. I left the edge .020" thick before sharpening. Paul Bos heat treated it. Paul did a triple draw at 1000deg
and he cryo treated it. The final hardness came out to 58Rc.
Here's a pic of the knife.

This particular knife has been in the hands of a US Marine for the last 10 months. He has done some serious work with the blade and has had no complaints. The knife has perfomed admirably.

My personal carry knife (I do volunteer search & rescue) is out of D2 as well. It has been heat treated the same way as the one above. It has a 6" long, 3/16" thick, 1-1/4" wide blade. The edge was left about .020" before sharpening. I have put this blade thru HELL over the last 3 years and have had no problems with performing such chores as digging, prying, and general cutting.

Barry, thanks for the details, very nice looking blade. I have used D2 with a similar heat treat and have had the same experience. One final question, at what angle do you grind the edges for heavy work blades like those?

-Cliff
 
Cliff,

I just step up to the grinder and put an edge on it. I really don't measure the angle.
Sorry, if that is not what you wanted to hear.
