Gardening Niwaki Tool Care | Niwaki Twin Diamond File

Rather Like A Heavy Duty Nail File, This Twin Diamond File Works In The Same Way But For The Coarse Sharpening And Re-Setting Of Old Blades. Double Sided, The 120 Side Eats Through The Steel To A New Edge, Then The 300 Gives A Crude Finish Before You Move Over To A Whetstone To Get A Decent Edge.
