Does anyone know where to get the letter opener blanks that have a mandrel large enough to do Peyote stitch?  What I have been finding has a 1/32" mandrel for beads.  Thanks.

Found some letter openers with a larger handle at the below listed sites, the sites are all for supplies for woodturning but the parts can be used to bead around instead of doing woodturning. 

Hope this helps you.

Thanks LaughCat.  I had seen the woodworking sites, but I wasn't sure if they are the same thing.  Well, now I have plenty of places to get them.  Thanks again.
