Hi,
The #731 is a crowner, looks like a mulesfoot but half round instead of a V. About 5/16" wide. Looks like Craftool #727 but smaller.
#862 is a pear shader or thumbprint about 1/8" wide by 5/8" long with horizontal lines. I have Craftool #861 but is has verticle lines.
The other, #873, I can't remember what if is, a pattern I have obviously seen in one of my catalogues.
I think I could duplicate these tools from Barry King but thought that Craftools might be a little cheaper if I could find them.
Thanks for your interest.
Gary
