DMT DuoSharp 8-inch Sharpening Stone, Dual-Sided: Coarse/Fine (320/600)

1 item left

Innovative, multi-patented DuoSharp® Bench Stone is a precision flat, two diamond surfaced sharpener guaranteed to provide consistent, even sharpening every time. 8" DuoSharp® Bench Stone, an excellent counter and bench sharpener, with a larger, wider diamond surface for sharpening a variety of edges. 

This DuoSharp® features two sides of interrupted diamond surface sharpening and is the ideal benchstone for the shop or kitchen, especially when paired with the optional DuoBase™. The 8 inch length is perfect for chisels, plane irons, chef knives - practically any tool. While providing a generous sharpening surface, it is engineered to be rugged, lightweight and compact - great on the jobsite! The interrupted, or polka dot pattern is extremely efficient as the recessed holes collect metal fines to prevent loading. On the other hand, the continuous diamond surfaced stone (Dia-Sharp®) is slightly less aggressive, but as effective in sharpening. Selection is a personal preference (these Duo-Sharp are dual-sided and much lighter, and so are definitely more portable and affordable). Click here to read the use and care instructions.

Surprised me!

I was looking for some decent diomond stones to restore some old chisels and planer blades. I didn't want to use my shapton stones as they would take a ton of wear. This one surprised me. Great combo, even better price! Don't hesitate, it really is worth every penny.
