Got this a while back and thought I'd share. It's a Warner Hudnut Reelshave. Introduced in 1964, they never really caught on. It uses a band blade that is in the cartridge in the picture. Works like a cassette tape. Blade gets warn, advance the band to a fresh segment. I have not tried it yet. Too much other stuff to play with. I love the way it looks though.
