Once you’ve invested in good quality pruners and loppers it is important to maintain a sharp cutting edge. Sharp pruning and cutting tools produce cleaner cuts that are easier to perform and are better for the health of the plant. DMT sharpeners are made with monocrystalline diamonds, a strong single crystal structure that doesn’t break apart with use, bonded in nickel to steel with recessed dots for chip clearance. Diamond is the hardest material and is the most efficient sharpening abrasive requiring just a light pressure to produce a sharp edge with just a few strokes. The two-in-one Diafold has two grits, fine and coarse, on reverse sides for added versatility and convenience. By using the coarser side first, and then moving to the finer surface, a razor sharp edge can be achieved. Use coarse to restore a dull edge and then fine to maintain an edge. Folding plastic handles protect the Diamond Sharpener when not in use. 9½”/24 cm open, 5”/12.5 cm closed. Made in USA.
