Take your sharpening anywhere with the ready-to-go Dia-Sharp credit card sized diamond sharpener. Fits easily in pocket or wallet. Comes in convenient vinyl color-coded carry case.
Note: This credit card size diamond hone works amazing as a slurry stone! Just rub the top of your waterstone for 10 seconds and see how quickly you build a rich smooth slurry. For the most consistent results with synthetic stones like Naniwa just rub enough to removed the black carbon build up and then rinse with water for a fresh new fast cutting surface.
