Unique All-In-One Knife Sharpening Kit

We're thrilled to introduce the new Shapton Glass Stone Seven Knife Sharpening Kit. The G7 Kit has everything you need to sharpen knives; stones, holder and diamond lapping plate beautifully presented in one box. The entire kit gives you the high Shapton quality you would expect. There really is no other knife sharpening kit like this.

7mm Thick Abrasive Layer

The "Seven" in the name of the Shapton Glass Stone Seven, refers to the 7mm thick layer of abrasive on each stone. This 7mm of abrasive is 2mm thicker than the 5mm layer found on the Shapton HR and HC Series Glass Stones. Like Shapton's other Glass Stones, the stones in the G7 Kit are mounted to a 5mm thick glass base, making for stable, long lasting sharpening stones.


As you would expect from Shapton, the G7 Stones are splash-and-go. Simply get them wet and they are ready to use. No need to soak them before sharpening, so you can get back to using your sharp knives faster.

Comprehensive Range of Grits

The grits of the G7 stones are unique, they are not simply smaller copies of the other Shapton Glass Stones. The selection of grits in the kit provides a comprehensive range for complete sharpening of knives.

The three grits are:

  • 25 micron - about 600 grit. This grit is used to efficiently shape an edge on dull knives.
  • 6.70 micron - about 2500 grit. This grit is used to refine an edge shaped on the 25 micron stone, or to refresh the edge on a knife that needs only a light touch up.
  • .44 micron - over 30,000 grit. This grit is even finer than the .49 micron/30,000 grit stone found in the HR series, and we have no other stones so fine. It is used to put the finishing touch on a razor sharp edge.


The Stones of the G7 are 160mm x 37mm, or about 6-1/4" x 1-7/16". This is a bit smaller than the 210mm x 70mm, or 8 1/4" x 2 3/4", size of the HR and HC series stones. The G7 stones fit snugly into the Stone Holder.

Stone Holder

Functional and beautiful, the G7 stone holder is made of fused layers of glass with sturdy non-slip rubber feet and stops. The stones are securely held in place, and the all-glass construction is sturdy, stable and easy to clean.

Diamond Flattening Plate

The 160mm x 37mm diamond plate has deep grooves for clearing waste material while flattening and is backed with sturdy rubber, making for a comfortable grip. To flatten a stone, place it in the holder and mark its surface with the included pencil. Then, using plenty of water, rub the diamond lapping plate over the stone until the pencil lines completely disappear to ensure a flat, smooth sharpening surface.

Marking Pencil

Shapton has even included a pencil in the G7 Kit so that you can mark the surface of the stones prior to flattening them. This truly is an 'everything you need' package.

Made in Japan

All Shapton GlassStones are made in Japan. We have been a retailer of Shapton products for many years now, and we have always found these stones to be of consistently high quality.

Sharpening Supplies is an authorized retailer of Shapton stones.

Q. Are the stones made of glass?

A. The stones themselves are not made of glass. The Shapton GlassStones are backed with 5mm of glass to provide a firm, flat surface for which to adhere the ceramic water stone abrasive material.
