Anyone who uses a knife regularly knows that having a sharp blade edge is much safer than trying to make a dull blade do the job. Designer Tom Stokes created this compact sharpener so it would be easy to have along, and keep you sharp.
You simply hold it firmly on a hard surface, place the rear of the blade edge into the "V" of the carbide sharpener blades and draw the knife through, pulling towards you.
This handy tool also features a flathead screwdriver, small channel blade/cutter, and bottle opener. The Stokes Keychain Sharpener also comes with a split-ring for easy carry attachment.
