Whetstone Amakusa Whetstone Red Torato Natural Whetstone 30 Type ・30 type: Approximately 19.5 x 6 x 4 cm, approximately 1076g Compare with #AmakusaTakarajima's Amakusa Whetstone. This belongs to the category of medium to coarse grit. I think it is suitable for removing rust and for agricultural tools such as sickles. You can use any surface for sharpening. As it is a natural product, there are hard parts, soft parts, areas with air bubbles, spots, and slight chips. The air bubbles are favored because the sharpening slurry accumulates there. It may rarely crack. We cannot provide support for that. Please purchase only if you understand that it is a natural product. The clearer the wood grain, the higher the possibility of cracking from the darker areas. [Reference Explanation] 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 kitchen 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 ◎Nakajiro (Special Prepared Water): Intermediate between red and white ◎Johaku (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 #AmakusaWhetstone #WhetstoneForSharpeningKnives #WhetstoneForSickleSharpening #AmakusaShiro #WoodGrainStone #Torato #Bisuito #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.
