OBG,
Does it appear to you the handle was made and then tang inserted? ...or that the plastic was poured into a mold over the tang?

If the latter then, depending on the bond between plastic and steel in this case, it may well just slide off with a little work.

(I'm at Ragweed's site now looking at the Moras for the umpteenth time, and wondering why I haven;t ordered one of these knives. See what you started, Billy?)
