Sharpen Dull Tools With This Handy Credit Card Sized Diamond Stone

Take your sharpening anywhere with the ready-to-go Dia-Sharp credit card sized diamond sharpener. It fits easily in your pocket or wallet and is super handy to have in the shop. We use these 'credit card' sharpeners on our router bits and saw blades and they really can bring a tired carbide edge back to life. Why do we love using DMT sharpening stones? Because they're fast, easy, and the results are excellent. A bonus is that it's not messy, you don't need oil - sharpen dry or with water. Durable construction will provide years of consistent performance and reliable service. Each sharpener comes in a convenient vinyl color-coded carry case. Measures 3-1/4" x 2" x .05".

Customer Reviews (5.0 / 5 · 5 reviews)

William ★★★★★

The credit card size is genius—it slides right into my wallet without adding bulk. I used it to touch up my pocket knife before dinner prep and it bit into the steel immediately.

Brian Y. ★★★★★

Pulled it out at a campsite when my pocket knife wouldn't bite through a tomato, and the diamond surface had it slicing clean in under a minute. Fits in a jeans coin pocket so it's always on me, no bulky case needed.

Riley ★★★★★

Slips right into the wallet’s card slot, so I actually carry it now instead of leaving a bulky stone at home. The diamond surface is surprisingly aggressive for something so thin—brought a neglected pocket knife back to slicing paper in a couple of minutes.
