Nice bayonet!
I have an Arisaka bayonet that grandpa brought back from the "Big One"
Well, actually it's only half a bayonet as his C/O made his whole company break or disable any working "collectables" they brought home.
I started modding it into a tanto a decade or so ago then got sidetracked halfway through the project...will post up some pics of the WIP if I come across it soon...
