Whetstone Amakusa Whetstone Special Prepared Water Medium White Natural Whetstone 30 Type ・30 type approx. 19.5 x 6 x 4 cm, approx. 1192g #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. Stainless steel knives OK! The price is also cheaper and more affordable than the upper white 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 places, soft places, and places with air bubbles. The air bubbles are preferred because the sharpening slurry accumulates there. There may be slight chips or, rarely, cracks. We cannot handle those. Please purchase only if you understand that it is a natural product. [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, 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] ・10 type approx. 21.5 x 9 x 7 cm, approx. 3200g ・15 type approx. 21.5 x 7 x 6 cm, approx. 2200g ・20 type approx. 20.5 x 7 x 5 cm, approx. 1700g (special order) ・30 type approx. 19.5 x 6 x 4 cm, approx. 1130g ・60 type approx. 16.5 x 4.5 x 3 cm, approx. 600g (white only) ・80 type approx. 15 x 4 x 3 cm, approx. 420g (unsorted) #Whetstone #Amakusa Whetstone #Whetstone for sharpening kitchen knives #Whetstone for sharpening sickles #Amakusa Shiro #Wood grain stone #Torato #Prepared Water Whetstone #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.
