Never thought about that! It might well predate any production 'western kami' !
Oh, no doubt a razor, made by a good German maker. The blade is downright normal for a top-notch double-ground Solinger. Look at the end of the tail. Just like a normal razor. A different thing, for certain!
I think you made that in your laboratory and posted it here to confuse us....I saw the thread with just the tail of that peeking out of some cauldron.
Some type of German / Japanese Frankenstein razor you've created?
