Amakusa Natural Whetstone Special Prepared Water Medium White, Natural Whetstone, Type 30 ・Type 30: Approximately 19.5 x 6 x 4 cm, Approximately 1162g #Compare with Amakusa Treasure Island's Amakusa Whetstone. This is an Amakusa whetstone that is a mix between red (Torato) and upper white. The mining of upper white Amakusa whetstones has become difficult. Therefore, the hybrid whetstone... Medium White has appeared. OK for stainless steel knives! The price is also cheaper and more affordable than upper white whetstones. It falls into the category of medium grit whetstones. I think it is suitable for sharpening knives, carpentry tools, and agricultural tools. You can use any surface for sharpening. As 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 chips or, rarely, cracks. We cannot provide support for this. 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 knives, carpentry tools, and agricultural tools. Recently, due to the spread of artificial whetstones and the aging of producers, they have become less available in the market. This time, we will deliver it directly from the local Amakusa to those who can use it. *The grit size varies for each natural whetstone. ◎Torato (Red): Reference grit size around 500-800 ◎Medium White (Special Prepared Water): Between red and white, Nakajiro ◎Upper White (White): Reference grit size around 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 (Special 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 #WhetstoneForSharpeningKnives #WhetstoneForSickleSharpening #AmakusaShiro #WoodGrainStone #Torato #PreparedWaterWhetstone #Oyano *We plan to send it via Yu-Packet Plus. *Discounts are not available. *Please comment if you wish to remain anonymous. *This is an inexpensive whetstone that can be used normally, so please refrain from asking advanced questions.
