haft is a tad short for an executioner's axe
(i suspect it was a teeny bit longer in it's working life)
there is a very similar one on ebay at the moment. haftless. marked "AD" on one side, "CP" on the other. sadly we cannot discuss it, so no picture. try googleing images for 'executioners axe'.
here's another. hired him for my quickie divorce. a lot cheaper than going thru the courts as henry the 8th found.
