A2 tool Vs D2 steel...

[KCkc]

So why is it preferred over D2 ?
Isn't it true that D2 will retain the edge longer and has a higher carbon content (so not as easy to rust ??) ?

Specs from AG Russell:
Non Stainless Steel: Carbon, Manganese, Chromium
A-2 : 0.95-1.05, 1, 4.75-5.50
D-2 : 1.40-1.60, 0.6, 11.00-13.00


Thanks, I am still trying to learn more about CRK.
BTW, I like their solid feel A LOT

on some knives designed for hard use,like CRK knives,a2 is used for it's impact resistance. d2 is good for keeping it's edge,and will cut all day,but some knives are used for other purposes than cutting ie.chopping and digging,and a2 is an excellent choice for that type of knife.

Both are good cheap readily available tool steels and I don't think you will notice any difference in edge retention with normal knife use.

thanks now I understand better = )

D2 in the knife world, considered a semi-stainless steel. It is the chromium content that gives it it's rust resistent properties .

D2 may hold an edge for a while, but it's brittle.

Reeve initially used D2, but discontinued it in favor of A2. The main reason A2 is favored, as said, is that A2 is significantly more impact resistant than D2 and most other cutlery steels, hold CPM-3V. In a fixed blade used for hacking, impact toughness should ideally be priority number one, which is likely why Reeve discontinued D2. Reeve does not over-harden like some makers which does not seem to affect edge retention much at all, but it indeed increases impact resistance.
