By the way, what's the difference between a scabbard and a sheath?
Initially, a scabbard was a splint of wood, from schal (a rind) and bord (a board) Long "scale-boards" were used in making sheathes for swords. Through a bunch of linguistic gymnastics, sheath appears to be derived from the same understanding as splint or veneer of wood used in making thingees to hold swords, daggers, and so forth.
In common usage, though, it seems that scabbards are for long things -- swords and rifles -- while sheathes are for smaller things like knives.
We can avoid the distinction by putting Pawpa's gorgeous box knife in a holster.
