Picked up another JNat and what was labeled a Kuro nagura (think it's a Tsushima nagura, correct me if I'm wrong). The JNat is an Ozuku (kiita with nashiji and goma?). It's harder than my last JNat and from the limited times I've used it seems like it's capable of producing a fantastic edge. It's got a big inclusion, but it doesn't seem to affect the edge (yet). I cut the chipped corner off to make a tomo nagura.













Cheers,
