Shapton Glass Stone 500 Grit Sharpening Stone, Double Thick

6 items left

Shapton Glass Stone, 500 Grit, Double-Thick, #50106. 

210mm x 70mm, 10mm thick (total thickness is 15mm: 10mm of abrasive bonded to 5mm glass plate). 

Comes packed in a Pro/Kuromaku style plastic case which can also double as a basic stand (though a proper heavier holder is strongly recommended).

This is a special double-thick version of the very popular 500 grit Shapton Glass Stone. If you do a lot of sharpening, this is a great choice to get extra life from this excellent coarse stone.

Shapton GlassStones are very fast cutting and long-lasting. The ceramic abrasive is permanently bonded to a glass plate so the whole unit is very flat and very strong. The abrasive is extremely consistent and dense so you have a great feel and can produce very precise and clean edges, plus these have the convenience of splash-and-go sharpening (do not soak these stones).

The Shapton stone holder (sold separately) is designed to fit these stones perfectly and is quite heavy and tall, providing a great workstation. The more affordable Naniwa universal/adjustable stone holder also works fine for these stones. The Naniwa rust eraser is also popular for quickly cleaning your stones of embedded metal particles.

Of course you'll eventually need to flatten your stones too, so consider one of the Naniwa flattening stones for a great budget solution, or one of the DMT or Atoma or Shapton diamond lapping plates to get your stones super flat.

Made in Japan.

Great Stone

Shapton stones are the best for their price point, they are very good quality. Glad to have a Canadian source to buy them. Service was extremely fast. Only good things to say about Pauls.

Excellent Stone

I really like the feel of the stone when sharpening with it. It gives a lot of feedback and I find it easier to get my angle. Moves metal very quickly.

Great stone

I have multiple different stones most of them naniwa, this is my favourite coarse stone it cuts as fast as my 220 and 400 grit naniwa traditional and professional but is a bit smoother and does not load up. Very impressed with this stone extremely good value and it seems to work well on my rock hard fujiwara denka and on my German knives as well. Great purchase I will buy shapton again for sure.

Paul Ostler
Shapton Glass 500

This is a quick stone removing metal nicely without loading up.
It is a great stone for German steel kitchen knives and all anyone really needs for most knives.
A finer stone would be required for raw meats and such but the 500 is a workorse.
Great stone!!

Love this stone

I sharpen knives professionally on a daily basis. Coarse stones are the cornerstone (s) of my process. I start every knife on a coarse stone and the all stones wear out over time. So to have this excellent product available in an extra thick version is fantastic. Shapton Glass stones excel at abrading any steel but especially very hard steels that some other brands may struggle with. With over 50,000 knives under my belt, take my word for it, it’s an awesome abrasive and will lead to the building of skill, confidence and a sense of satisfaction.
