t1(18% w) is very tough and not brittle ( i have read from from metal book) for cutting wood .in industry is hss for cutting metal.t1's hrs about 64(need not heat treatment)
usually,in order to reduce cost ,some metal cutting use m2(8%w) as substitue .
d2 is a tool steel ,as mentioned ,it contain high content of cr , cause ''stainless''
for cutting hard metal(not me!),such as stainless steel,people like to use m35 (contain cobalt) but it is brittle .
certainly,t1,m2 ,easily to get rust.hence ,those hand knives use stainless steel ,but high quaility stainless steel are expensive with good wear resistance ,tough,hardness ... such as cv30,ats34 ,sgps(fallkniven).
