Natural Whetstone I don't know the details, but this is a natural whetstone. A carpenter who worked for 30 years used it, so I'm sure it's genuine, but I don't know how to judge it, so please make your decision based on the images. It can be used or displayed. Please judge the dimensions by looking at the images. The price is what the carpenter said it was worth, or maybe a little higher. #diy #DIY #chisel #chisel #chisel #setofchisels #setofchisels #carpenter #carpentrytools #tools #collection #blades #edge #chisel #setofchisels #chisel #tools #plane #plane #chisel #tools #plane #KenjiUsuhi #Tomoura #ShujiKogata #sunpachi #sunroku #sunyon #sun #bu #traditionalcrafts #shave #old #new #used #readytouse #mosaku #whetstone #naturalwhetstone #suita #akarenge #renge #naturalstone
