KAI Combination Sharpening Stone, grit: 400/1000 - Japanese knife sharpener for coarse and fine sharpening - sharpening stone 400 1000 whetstone for knives usable surface 18 x 6 x 3 cm

It is better than I expected. Thank you very much.

I own and use this whetstone, KAI is a well known knife brand and can be trusted. It just takes some practice to learn how to use it. The 400 (荒砥石) is used for very blunt knives or knives with visible gaps in the blade. The 1000 (中仕上砥石) is used for everyday maintenance. There are youtube videos but basically the angle is quite important and the stone needs to be kept wet (if it dries, you can add more water to the tray which will soak into the stone). My only issue is that the set retails for £11.36 in Japan and £40 is a high markup even considering the import job.

good stone

Quality product, so long as you know how to use it. creates a good edge.

This is not a good buy. I used once and was very disappointed. Poor quality imported imitation. Even if it was half the price I would not recommend.

鋼製の万能包丁を研ぐために購入しました。 説明書が分かりやすく、その通りに研いでみたところ、切れ味がしっかり戻りました 。普段あまり包丁を研がない私でも、問題なく使えました。 #400と#1000の砥石がセットになっているので、刃こぼれの修正から仕上げまでできるのも便利です。家庭用としては十分な性能で、日本製という点も安心感があります。初めて砥石を使う方にもおすすめできる商品だと思います。

Rispetto ad altre pietre che ho provato affila molto meglio, permette di ottenere buoni risultati in poco tempo, altamente consigliata rispetto alle altre scelte presenti su amazon

Der Stein mit seinen beiden Körnungen eignet sich hervorragend zum Schärfen von Messer. Der Halter ist rutschfest, so dass man sich auf den Schleifvorgang konzentrieren kann. Der Stein ist sein Geld absolut wert.

Good design with a tray below to capture the water. Use for sharpening knives.

EXCELLENT PRODUCT.
