my desk knife/letter opener is a WW11 german SA dagger, double edged, about 12" long w/brown wood handles, and an inscription, alles fur deautschland (spelling) nazi eagle on handle, made by carl eichhorn, solingen,along w/sheath, brought home from italy by my dad in '45, he got it off a captured prisoner of war, along w/some other stuff - still have a P38 w/a 90+% holster, and a '98 mauser KAR, in great condition,(and a luger and berreta too) have NEVER seen a better one that was original, was brand new when my dad ' appropriated 'it in WW11 from a stack of them as big as a house and sent it home in pieces lol - but that is my'desk knife;its a lotta knife - its also my favorite, because of its history, my dad kept it in the closet for years, i dont think it had been sharpened since '45, but i touched it up a little, a great knife(looks a lot like a gerber mark 1 on steroids), w/a lot of history, some guys at the gunshow had one similar, but not as good a shape, for $200 if memory serves, but of course, its not for sale.............
