The KJ-140 Wide Centering Knife Jig is designed to center long, flexible knife blades for optimal, symmetrical results. Its 5 1/2" wide clamp provides excellent stabilization for flexible blades, and it effectively centers tapered knives, holding them firmly in place. The jig includes an extra stop for tall knives like cleavers and allows for shaping a slightly convex edge by moving between the two stops. Constructed with a robust design featuring zinc-cast clamps and durable composite stops, the jig is well-balanced with most of its weight focused on the clamps for a more stable feel during grinding. It slides smoothly with low friction against the universal support and is compatible with Tormek T-4, T-8, and older models. This jig ensures symmetrical sharpening, centering knives of any thickness up to 10 mm (7/16"). Achieve sharp and even blades with symmetrical bevels at the same angle on both sides, suitable for longer knives or flexible filleting blades. Restore or choose your preferred edge angle by allowing the jig to rest freely on the Universal Support to follow the blade's curve.
