Renaming Attention - Gritomatic

Renaming Attention

Gritomatic synthetic stones made of silicon carbide and aluminum oxide can be labeled in either FEPA-F or JIS grit scale. To make grit uniform and customer-friendly, we have started transition to the japanese (JIS) grit scale for all Gritomatic waterstones. Old naming: F 120, F 220, F 400, F 600, F 1000. New naming: 120, 240, 600, 1000, 2500.

As the owner of Gritomatic online store I'd like to use this blog to talk with you and share my knowledge and experience in sharpening. English is not my native language, I am sorry for any mistakes and really hope it will not become a barrier between us. I will be happy to receive feedback from your side.
