The Large Sasquatch blades are numbered in sequence. Any other etching is a chargeable option.
We do not have this visibility.
Some assumptions (could be wrong):
a) sequence numbering is dealer-managed
b) shop charges dealer for sequence-number etching
c) dealer includes that cost in the "base price" for their grind
I've been wrong before, so take it as a thinking point and not solid fact.
Some collectors like to buy the Large and the Small made up to match, and have the Small numbered the same as the Large.
Yup, I have a pair as you described. Not quite "numbered the same" as user-requested numbering happens on the "down" side of the blade.
