5. Operating Instructions

5.1 Sharpening Process

With the knife securely mounted in the KJ-140 jig and the jig attached to the universal support, adjust the universal support to achieve the desired sharpening angle. Gently guide the knife, held by the jig, across the grinding wheel. Maintain consistent pressure and movement to ensure an even bevel. The jig's design allows you to follow the contours of various blade shapes, from straight to recurve.

5.2 Centering Feature

The KJ-140 jig automatically centers the knife blade, regardless of its thickness or geometry. This feature ensures that the grinding action is symmetrical on both sides of the blade, eliminating the need for manual adjustments to achieve an even bevel. This is particularly beneficial for knives with varying blade profiles or tapers.
