But, best of all, I see that Melen was right,

isn't this a tool to cut strips of leather?

Yes

I forget the name of the tool tho. 

It is called a Lace Cutter.  or Lace Maker. 

I bought mine from Spotted Pony Traders while attending the Pennsic War ... unofficial. 

I found another online supplier ... Rude Dog Leather (doncha' just love that
name???) sells a Lace Making Tool. 

Thanks to everyone for playing ... Please stay tuned for some show and tell images to follow ...
