Product is strong and probably better than other products in similar price range.Its aggressive and diamonds didn't get dull or separated from the plate.I bought the plate for woodworking tools specially mora knives and gouges and a bit flattening the water stones and found that the plate is a minimally cupped in the middle.But the flat parts on two sides are completely enough to flat grind a small mora knife.This price it's a Perfect plate and if you are not really into flattening water stones and only sharpening its perfect ( with a bit more care for flat grind knives like mora ).Other than that for pocket knives and kitchen knives and outdoor knives the very minimal cupping doesn't matter and go for the plate.I suggest.

Świetnej jakości towar.Oselka dobrze zbiera.Solidna.
