These are whetstones that were acquired due to a carpenter's retirement. The finishing whetstone is a genuine natural whetstone used by the carpenter. (Origin and brand are unknown.) *Not for individual sale. (Sold as a set of 3) Left photo: *Natural finishing whetstone, likely #8000 to #10000 grit. This whetstone produces a lot of mud and provides a good sharpening feel. 22cm x 5.8cm x 6.7cm Right photo: *Medium grit whetstone, King Deluxe Stone #1200 grit. (Used very little, almost new condition. The box is damaged.) 20.7cm x 6.6cm x 3.4cm Middle photo: *Coarse grit whetstone, approximately #200 to #300 grit. 23cm x 7cm x 4.5cm *All three stones have flat surfaces and can be used as is. *Everything in the photos is included. *Natural whetstones are becoming extremely rare due to the closure of mines, so how about taking this opportunity? *(Especially finishing whetstones, which can only be mined in Japan, are very rare.) I have taken as many photos as possible, so please understand the nature of natural whetstones before purchasing. Thank you.
