DMT W7 diamond whetstone
The DMT W7 Mini Diamond Whetstone is a compact, portable diamond sharpening stone designed for field use, toolboxes, skate kits, and quick edge maintenance. It uses DMT's monocrystalline diamond abrasive surface, which cuts faster than conventional oilstones or waterstones and stays flat throughout its life.

Common Use in Speed Skating
In speed skating and long-track/short-track blade maintenance, the W7F (600 grit, red) is frequently used as a burr stone after sharpening. Its small size makes it ideal for removing the wire edge from skate blades without carrying a full-size bench stone.
Manufacturer Description
A portable enhancement to any tool kit, providing quick edge repair anywhere. Durable construction delivers years of consistent performance, with a diamond surface that sharpens faster than conventional stones and requires no oil.
If you're using the W7 specifically for speed-skating blade maintenance, I can also explain the differences between the W7F (red 600 grit) and W7E (green 1200 grit) for deburring and edge finishing.
