SR101 vs 01

[RWT]

How do these two steels compare?
1. Edge retention
2. Toughness
3. Easy of sharpening
4. Rusting
5. Roll vs. chipping

Do any custom makers use SR101? Is one better suited for a hard use hunting knife than the other?

I believe Sr101,is a proprietary steel by Busse and is a modified 52100 hope that helps
