Naniwa Diamond Square Whetstone DR-7560#6000

This diamond impregnated resin stone is excellent for hard metals, such has my high rockwell plane blades and chisels. It cuts fast (for 6K grit) It does tend load up, but it does not seem to affect the ability to continue cutting. When you do have to clean it, it's easy. For me, going from this 6K to a strop with diamond paste results in hair splitting sharpness that fits my circumstances. This diamond stone should last a very long time, and I'm pleased with the results.

Nice stone. A bit on the pricey side. Have used it on about 20 knives so far and satisfied with feel and results.

These are the top of the line. Great product.

I have a Creely MAKO knife with REX 121 steel. That's HARD steel. Shapton Glass stones would not do it. Ceramic would not do it. This stone, coupled with a Trend 300/1000, and a Naniwa Diamond 3000 got the knife sharp. The stone is smooth and flat. It does not feel rough like many other diamond stones. It's a good stone if you like diamonds or if you need diamonds because of special needs.

Puts a polish on my ZDP-189, HAP40 and SG2 knives with ease. Highly recommend. Dress with polish stone.

I've been a professionally sharpening high end hair shears for nearly 30 years.The stones I'd been using daily, have been showing wear for the last year.I've searched for my originals but couldn't find them.I spent nearly $500 in the past 4 months and couldn't duplicate the results of the originals.FINALLY I found what I've needed!1000, 3000, 6000, grit stones.They may have cost me an additional $500 for the 3, but would gladly would buy them again!

Nice addition to my set of sharpening stones. This is so smooth and brings my knife edges to that next level. I highly recommend this to anybody that likes to keep their kitchen knives sharp!

Very Good
