The Osborne Edge Bevel is a premium edge beveller (Made in America). It has a cutting edge that removes a piece of leather from a strap edge. The tool can be used to remove the edge from the top side and also the back of leather. After using the Bevel it is recommended that the leather edge be polished with an edge slicker. Size No: 4 takes the most amount of leather off . Please note the tool works better on stiffer leathers and may be difficult to use on soft floppy leather.
