jay,

Rob is right . This jig setup consists of two parts, sold seperately or as a set. The angle setter is a flat piece of milled steel with a 5 sided , rotating fisture at one end. Each side is a different angle. You use this to set your blade at the proper angle in the roller guide.

Then you just run your blade and guide combo over your stone, or piece of plate glass that you have attached the appropriate sand paper grit to. The actual Roller Jig has a feature that allows you to set an extra few degrees of elevation so you can put a very fine edge on the last few thousnads of an inch of blade, getting a very sharp edge. My blades were in terrible shape from trying to hone them without a guide and are now shaving sharp.

Price was about $34.00 for the set from Amazon.com. There was a free shipping offer on this item that may still be in effect.
