Additional information

The credit card-sized diamond sharpening stone offered by Gaignard Millon is an industrial diamond sharpening tool, manufactured by DMT (Diamond Machining Technology), an American company specializing in precision diamond abrasives.
Unlike traditional gemstones (corundum or Japanese diamonds), this stone is constructed on a highly resistant steel plate entirely covered with single-crystal micro-diamonds. These industrial diamonds work very quickly and maintain a smooth surface even after numerous cycles of use.

The 82 mm × 51 mm × 1 mm size (about the size of a credit card) makes this stone very practical to handle and easy to store in a toolbox or workshop kit. The diamond finish is ideal for quickly maintaining edges, shaping, or resharpening various blades and tools, even those made of very hard steels (high-speed steel, carbide, or ceramic).

An important characteristic of diamond stones is their low wear: the surface remains flat and usable for a long time, which guarantees a lifespan far superior to conventional abrasive stones.

👉 Important: during use, the stone must be constantly wet with water to optimize gliding and prevent the edges from overheating.

Expertise

Gaignard Millon

Expertise forged through workshop experience: we compare, measure, and test each item on various types of wood. Selection guided by cut, ergonomics, and durability. A standard confirmed by professionals: École Boulle, the Louvre Museum, the Musée d'Orsay. As enthusiasts, we select only the best tools.

Workshop check & sharpening ready to use

Every tool passes through our hands before shipping: visual inspection, geometry, flatness, and deburring. If necessary, we sharpen it on a Tormek system for a consistent angle, and a clean, durable edge. The result: a tool that cuts cleanly right out of the box, with no time wasted at the workbench. Tested on wood, wiped down, protected, you receive a tool ready to work.
