Tool Care Niwaki | Niwaki Twin Diamond File

Double Sided Diamond File For Coarse Sharpening And Re-Setting Old Blades. This Is What We Use When You Send In Battered Old Shears And Secateurs With Nicked And Chipped Blades – The #120 Side Eats Through The Steel To A New Edge, Then The #300 Gives A Crude Finish Before Moving Over To A Whetstone To Get A Decent Edge. Use Dry. Indispensable.
