Today I took a few tools to work and put them in the hardness tester. The Veritas irons are A-2. The others are, well...whatever. I'd have to check Hock's site to verify what he uses. Anyway, the results (these should all be within 1 point on the scale):
Two Cherries 1/2" paring chisel: C61.5
Hock 1.5" plane iron: C62
Veritas skew rabbet iron: C62
Old Stanley block plane iron (30-40 years old): C59
New Stanley block plane iron: C61.5
New Stanley bench plane iron: C62
Vertias small plow plane iron: C61.5
Footprint 3/8" bench chisel: C62
I don't think this is anything groundbreaking. But I'm a geek and I wanted to know, and thought I'd share the results.
