Naniwa Abrasive Mfg Diamond Whetstone DR-7510#1000 (Japan Import)

Oh I like this. I like it very much!

I am a working professional and I've used many naniwa/shapton stones and I fell in love with this one quickly after first use. Tried this on a blue #2 yanagiba. Gave a very polished finish similar to a 3~5k grit stone and a smooth scratch patterns that are barely visible. I would just use this one stone only or maybe add a 3k if I need to make a second bevel.

Excellent item, works very well.

I ordered one of these 600grit resin bonded Diamond Stones for my knives made of modern super steels like my Bradford Guardian 4 M390 and my Benchmade Bugout S90V which are both hard steels. It seems to do really great with them. Has great feedback, great tactile feel and just like my Chosera ceramic stones i use for standard carbon steel knives it sharpens fast and seems really hard and slow wearing. I first had tried a Nanohone 1500grit resin bonded plate and it was an awfule stone that the binder used was too soft and didn't even do anything at all. The Naniwa is the way to go. Expensive yes, but also will last much longer than any CBN or plates with industrial Diamond sprinkled on top of adhesive smeared across a stainless steel plate. Which dont get me wrong those plates work great but do not last.

鉋や切出しを研ぐのに使っています。 よく研げて面が狂わなくてとても良いです。 研ぎにくくてしょうがない新品の粉末ハイスもよく研げます。 最近は6000まではこのシリーズの砥石で研いで、刃先のダレをできる限り抑え、最後だけ天然で仕上げています。 そうすると仕上げ砥石が刃先にちゃんと当たるので研ぎ上がりが早いです。 以前は硬さに定評のある刃の黒幕を使い、しょっちゅう砥面修正をしていましたが、それでも刃先がダレてしまっていたんだという事に気付かされました。 使うと結構すぐ黒く目詰まりします。 付属している小さい目立て砥石（GC？）は荒すぎるし面が狂う。 電着ダイヤで面出し&目立てした1000番の刃の黒幕で目立てをして使っています。
