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
