Here are some steel types used very often for knives.
High Carbon: not stainless, will rust, can be oil quenched for HT
1095 $3 a foot
O-1 $10 a foot
5160 $6 a foot
L6 $4 a foot
CPM3V Dunno..but more expensive
Stainless: Will not rust as easily as carbon (all steel rusts), but needs more complex heat treating
440C $10
ATS-34 $11
154-CM $11
CPM 420V Dunno...expensive
440V $28 a foot
BG-42 not sure..a little more than ATS-34
Tool Steels:
A2 $8
D2 $10
M2 ??
O-1
ATS-34
52100 round stock for forgers only, unless you get it forged into barstock for you
considered tool steels. More complex HT
Some ideas. get barstock, usually 1/8-1/4 thick, 1 to 2" wide depending on knife type. Flat ground is always a plus. Mill run is as it is, not truly flat, cheapest form, blanchard ground, much flatter than mill run, a little more expensive, precision ground, more expensive, but flat, great for folders, but often available in 3' sections only
The CPM stuff, and D2 are hard to grind, O-1 and 1095 are much easier and cheaper.
