is sr77 the same as s7 and if not whats the difference?
sykc says it differentially heat treats its blades.i know ranger does not.
how big of a difference does that make in a hard use chopper?
Scrapyard does not differentially treat the blades. They are through hardened as far as I know. The only Busse blade I'm aware of that is differentially heat treated is the Swamp Rat M6.
Justin has a very good heat treat for his blades as well, but they are all though hardened also.
