DMT Dia-Sharp Sharpener, Credit Card Sized

Portable sharpening solutions don’t come more convenient than the DMT “Credit Card” Sharpeners. Use em’ dry, and store them in your wallet; How’s that for a “diamond” level credit card!

Each rigid steel sharpening card is coated on one side with precisely graded monocrystaline diamonds, just like DMT’s larger Dia-sharp Stones. The shape and size fit nicely in the hand for comfortable and quick sharpening of pocket knives, small tools, and gouges. The range of three grits allows you to quickly repair a damaged edge and hone it back into sharp-shape.

There’s a lot of ways to use these sharpeners, and their size and shape make them great for camping, traveling, and work in the field.

Credit Card sharpeners also make an excellent and thin diamond file. In the Gramercy Workshop, we keep a set handy for removing burrs from milled slots and key-ways. Their thin, stiff shape, and tough diamond coating fits into places a regular stone or file just can’t reach.

Sharpeners come in a handy color-coded vinyl sleeve.

Shapeners measure 3.25″ by 2″ by .05″
