That's possible. People at blade said they Mic'd at .25" and the B-6 was supposed to be .25". I wonder if it's a way to save a little money. Like you said, to get down to .23" they probably use .25" stock. Therefore, a .25" blade would have to be cut from a thicker piece of stock, say .275".

Perhaps that's the last minute decision making that Jerry was doing in an attempt to save us all a bit of money. Who knows. That's just a guess.

Hooker, can you take a spine shot of your B-11? I always thought there was a taper after the Ricasso.
