Whetstone Amakusa Whetstone Special Prepared Water Medium White Natural Whetstone Type 10 ・Type 10 Approximately 21.5 x 9 x 7 cm, Approximately 3200g #Compare with Amakusa Treasure Island's Amakusa Whetstone. This is an Amakusa whetstone that is a hybrid between red (Torato) and upper white. The mining of upper white Amakusa whetstone is becoming difficult. Therefore, what appeared was a hybrid whetstone... Medium White. The price is also cheaper than upper white, making it an affordable whetstone. It falls into the category of medium grit. I think it is suitable for sharpening kitchen knives, carpentry tools, and agricultural tools. You can use any surface for sharpening. Since it is a natural product, there are hard parts, soft parts, and parts with air bubbles. The air bubbles are favored because the sharpening slurry accumulates there. There may be slight chipping or, rarely, cracking. We cannot provide support for that. Please purchase only if you understand natural products. [Reference Explanation] This is an Amakusa whetstone produced from the island of Oyano-machi, Kamiamakusa City, Kumamoto Prefecture, a place associated with Amakusa Shiro's war funds. It has long been favored for sharpening kitchen knives, carpentry tools, and agricultural tools. Recently, due to the spread of artificial whetstones and the aging of producers, it has become less available in the market. This time, we will deliver it directly from local Amakusa to those who can use it. ※The grit size varies for each natural whetstone. ◎Torato (Red) Reference grit size: Approximately 500-800 ◎Medium White (Special Prepared Water) Hybrid of red and white, Nakajiro ◎Upper White (White) Reference grit size: Approximately 1000 [Reference Sizes] ・Type 10 Approximately 21.5 x 9 x 7 cm, Approximately 3200g ・Type 15 Approximately 21.5 x 7 x 6 cm, Approximately 2200g ・Type 20 Approximately 20.5 x 7 x 5 cm, Approximately 1700g (Custom order) ・Type 30 Approximately 19.5 x 6 x 4 cm, Approximately 1130g ・Type 60 Approximately 16.5 x 4.5 x 3 cm, Approximately 600g (White only) ・Type 80 Approximately 15 x 4 x 3 cm, Approximately 420g (Unselected) #Whetstone #AmakusaWhetstone #NaturalWhetstone #WhetstoneForSharpeningKnives #WhetstoneForSickleSharpening #AmakusaShiro #WoodGrainStone #Torato #PreparedWaterWhetstone #Oyano ※We plan to send it via Yu-Pack. ※Multiple items can be discounted slightly. ※Please comment if you want to remain anonymous. ※This is an inexpensive whetstone that can be used normally, so please refrain from asking advanced questions.
