Super Diamond Card Sharpener Dual Grit Knife Tool

The Super Diamond Card Sharpener is a compact 3.25 in x 2 in sharpening card with 300 grit on one side and 600 grit on the other. The card is set to a 20-degree sharpening angle and keeps both grit stages within one flat, pocket-sized tool. Its size and abrasive style make it a purpose-built sharpening accessory rather than a general cleaning or polishing tool.

A lanyard hole is built into the card for attachment to gear or a retention cord. The thin rectangular format is easy to store with knives, fishing equipment, or field tools while the two-sided surface gives separate coarse and finer sharpening steps without carrying a second stone. It is made in China.

The Super Diamond Card Sharpener Dual Grit Knife Tool fits naturally into a knife-maintenance kit for users who prefer to handle routine edge care themselves. This type of sharpener is especially useful as part of a staged system where coarse work, refinement, and final touch-ups are handled separately. Keeping the abrasive surface clean and using it with the appropriate technique will help it perform consistently over time. Explore more sharpeners.
