Precision Marking Knife

The Zeptix Supplies Precision Marking Knife is the layout tool that makes your joinery lines tighter, cleaner, and more accurate than any pencil line can be. The single-bevel M2 high-speed-steel blade severs wood fibers at the layout line rather than pushing them aside, creating a channel that a chisel or saw can register against with zero wander. The flat back references flush against a straight edge, square, or saddle gauge, so the cut line falls exactly where the reference tool sits — no pencil-width offset to compensate for. The blade holds its edge through months of marking because HSS resists the abrasion of cross-grain fiber contact far better than standard carbon steel, and when it finally needs refreshing, a few strokes on a fine waterstone bring it back. The ebony handle is shaped for a precision pinch grip and fitted with a brass ferrule that adds balance and durability. A friction-fit leather sheath protects the blade in your tool roll or apron pocket. If you have been marking with a pencil and wondering why your dovetails never close perfectly, this knife is the missing piece.
