If it's spineless you need, try here but they come in packs of 1,000 (Group Buy?); http://www.razorbladeco.com/category/31-unbacked-single-edge-blades.aspx
Thanks for the link, but it's a little more involved than that. I think I posted it once here, or maybe another forum, but the spine comes off, a very large chunk of each side gets snipped off, the spine is trimmed to match, then the blade is slid under a little clamp thing that holds it down back into the spine that has to rest just so in the back of the razor, then the handle is threaded into the bottom of the clamp thing to clamp the blade down. Then I have a nap to regain my strength before I shave I really do love the shaves it gives though!
