Glen, you speculated earlier in this thread about just putting a thumb between the spine and the hone. Did you ever try that?

I'm thinking harder about that. Seems like you might have to use someone else's thumb. There'd probably be one lying around one of those old factories.

I like Gibbs's idea about the car door protectors. Those could flex along a smiling spine. The knife clips look a little clunky to use on smilers. If they had a little more of an oval profile I'd feel happier about them.

Cool thread. Damn these lost arts!
