My peanuts seem to be multiplying.
In my defense, the three yellow 'uns were bought in various states of "used" mostly for me to play around with fixing up. The two CVs had rust and some pitting, and the small blade of the SS one had a tip that had been broken/rounded off and didn't drop below the scales when closed.
I'm curious about the yellow one that has bolsters that look more square or less rounded than the others. Is that something specific to certain years? I tried googling to see if I could find other examples with bolsters like that but with no success.
From left to right/top to bottom, these were manufactured in 2003, 2005 and 2013 if I interpreted the tang stamps correctly. The middle one is the one with the more square bolsters.
Easier to see in these photos, maybe.
