I have forged them. afte red hot heating, twisted the shank above the head and drawn them out into "letter openers", ie more like office survival tools (Denny Crane, ie,... Boston Legal, ha ha). I even did a Marine version with a K-bar saw tooth on the back side.

They look pretty awesome. The top one in the pics has the best aesthetic.
