Whetstone Amakusa Whetstone Special Prepared Water Medium White Natural Whetstone 30 Type ・30 type: Approximately 19.5 x 6 x 4 cm, approximately 1075g #Compare with Amakusa Treasure Island's Amakusa Whetstone. This is an Amakusa whetstone that is between red (Torato) and upper white. It is becoming difficult to mine the upper white Amakusa whetstone. That's where the hybrid whetstone... Medium White comes in. OK for stainless steel knives! It's also more affordable than the upper white whetstone. 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 accommodate those. Please purchase only if you understand that it is a natural product. [Reference Explanation] The Amakusa whetstone is 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 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] ・10 type: Approximately 21.5 x 9 x 7 cm, approximately 3200g ・15 type: Approximately 21.5 x 7 x 6 cm, approximately 2200g ・20 type: Approximately 20.5 x 7 x 5 cm, approximately 1700g (Special order) ・30 type: Approximately 19.5 x 6 x 4 cm, approximately 1130g ・60 type: Approximately 16.5 x 4.5 x 3 cm, approximately 600g (White only) ・80 type: Approximately 15 x 4 x 3 cm, approximately 420g (Unselected) #Whetstone #NaturalWhetstone #AmakusaWhetstone #WhetstoneForSharpeningKnives #WhetstoneForSickleSharpening #AmakusaShiro #WoodGrainStone #Torato #PreparedWaterWhetstone #Oyano *We plan to send it via Yu-Packet Plus. *We can offer a small discount for multiple items. *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.
