I just saw a KK alloy steel single bit. I was looking at the pics later and trying to find a way to date head. It does not have the famous Keen Kutter Stamp like most. It has one like Operator's Connecticut Boy's Axe, also Post #11 and #19. All that I can find so far on the stamp is that if it is not the diamond and bar (common) then it is a forgery. That can't be accurate as I'm sure that many of you would be quite upset and would post your anger. So do those stamps that I reference above without the common logo predate the prettier stamp that has the bigger logo with the bar? I know they're not at all common, not my intention to offend. I just see more KKs with the big nice logo vs the Keen Kutter only as in the above mentioned pics.
My other question on this thread is on another recent find all it says is "Diamond edge" as well as "crucible steel" and "4" stamped. I was told it was a shapleigh that predated KK. Is that accurate? I'm not trying to sell these, I just want to pick out the oldest and best to pass on to my Grand Kids when they are ready. Quite young now and would likely sneak them off to show and tell. Could you imagine the headlines? Will wait a bit to hand them down.
