The axe radical and the axe kanji are exactly the same, with one minor difference. This kanji is also used as the bread loaf counter, probably because bread was so big and hard in the past that they had to use axes to slice them.
You imagined being back in time too good and now you're stuck using an axe to be a bread loaf counter for the King (きん) of England. You aren't sure which king he is or when in time you are, but he's mean and keeps eating all the bread you cut up with your axe.
Currently there are no similar looking kanji which exist in the WaniKani learning system
