The 1x6 Naniwa 320 Pro stone is a coarse stone used for profiling, repairs and initial maintenance on your edges. This stone is hard and aggressive, and really cleans up deeper factory scratches, making the transition from diamond plates and stones easier and cleaner. The 1x6 size is meant for use with the Jende JIGS for Knives, Edge Pro, Hapstone and TSProf sharpeners. It is also a great size for a slip stone, field stone or a pocket stone for knife sharpening on the go. 

1" x 6" x 5 mm in size and mounted to a standard steel blank, it is used with water only. It works best when soaked in water for a minute or two before use. Store in a dry place in between use. See also our full range of 1x6 Naniwa Stones.

Abrasive Material: Aluminum Oxide

Ideal place in a sharpening progression:

-- Starting grit for factory edge knife and profiling and repairs on a dull edge.
-- After any diamond grit plate to remove deeper scratches.
-- After lower grit sharpening stones (80, 120, 180, 220 grit)
-- After coarse belt grinder grits (60, 80, 100, 120, 220, A65, A30 Trizact grit)
-- Before progressing to a finer and/or medium grit stone (400 - 2K grit)

Hacks and Tips:

-- For a more aggressive stone, create a slurry by rubbing the stone’s surface with a smaller 320 grit stone, or a coarse or extra coarse diamond plate and some water. The slurry will be a pasty olive green.
-- Use a moderate amount of water when sharpening with this stone to avoid the black swarf from turning into a thick paste. A cleaner, more viscous surface will cut faster than a thicker pasted one.
-- Lap this stone with a coarse or extra coarse diamond plate, silicon carbide (SiC) powder, Jende Glass Lapping Plate, or low grit wet dry sand paper to keep it consistently flat and clean.
