Tormek KJ-45 centering knife jig

According to Tormek… With Tormek's patented KJ-45 Centering Knife Jig, you'll get symmetrical bevels with the same angle on both sides of the knife, regardless of the thickness or geometry of the blade. Whether you're sharpening a regular kitchen knife or a thicker, tapered hunting knife, you'll get the same results on both bevels of the knife without needing to reset the jig. The KJ-45 Centering Knife Jig fits most types of knives: household knives, chef's knives, craft knives and knives for hunting and fishing. It also works for the woodcarver's straight drawknives and the gardener's pruning shears.
