Thanks for the additional thoughts guys. I think I could use them for carving escapements, as Steve mentioned. (In fact, I got the idea from your blog Steve.) I'd also like to be able to cut "finger grooves" in things as Jim suggests, without my electric router.
Lowell, Mike - I'm very glad you pointed out that I need to actually handle them. That will keep me from having excess tools. Mike, I also found some carving tutorials on your blog/website I plan to look at.
I've got to find someone local that sells them and I'll take your advice and limit what I buy. I'm thinking maybe a 3/4" with a deep sweep for finger grooves, maybe a 1/2" that's more shallow and I might try a small V-shaped one.
Have a good weekend!
Fred
