Deulen Tools Jointer & Planer Knife Sharpening Jigs & Lapping Plates Dull jointer and planer knives leave ripples, tear-out, and burn marks on lumber. Deulen Tools solves that problem with precision-engineered sharpening jigs and lapping plates designed specifically for the flat, consistent edge geometry that jointer and planer knives demand. Re-sharpening in the shop rather than sending knives out for service saves time and keeps production running. Jointer Knife Sharpening Jig The Deulen Jointer Knives Sharpening Jig holds jointer knives at a fixed angle on the lapping plate, ensuring a reproducible bevel every time you sharpen. The jig eliminates the guesswork of freehand sharpening and produces a straight, flat edge that reinstalls true in the cutter head. Lapping Plate & Sandpaper The Deulen Lapping Plate provides the flat reference surface that jointer knife sharpening requires. It ships with sandpaper to get started immediately, and replacement six-pack sandpaper refills are available so you always have fresh abrasive on hand.
