Description

The Shapton Glass Stone HR 3.68 Micron #4000 Grit belongs to the Glass Stone series, known for its revolutionary design combining layers of tempered glass to provide excellent usability in a thin package.

This series offers a wide selection of stones, allowing users to achieve their desired blade finish effectively. The 4000 grit Glass Stone is classified as a fine grit stone, suitable for leaving a light polish and a refined edge on your blade. It is a valuable addition to your sharpening progression for optimal sharpness.

Contrary to the conventional belief that sharpening stones are large and heavy, Glass Stones are thin, light, and strong due to the layers of tempered glass bonded together. This construction provides excellent resistance to cracking or sudden breakage caused by external shocks, ensuring long-lasting performance.

The abrasives in these glass stones are extremely uniform, ensuring consistent performance from the first pass to the end of the stone's lifespan.

The Glass Stone series includes two types each of the 4000, 6000, and 8000 sharpening stones. The main difference between them lies in the abrasive agents used. Specifically, the Glass Stone series 50603, 50703, and 50803 are recommended for sharpening composite steel blades where steel has been forge-welded with another metal.

Each Glass Stone in the series is composed of a 5mm tempered glass backing plate bonded to a 5mm thick stone. Shapton sharpening Glass Stones are made with finely graded ceramic cutting media that requires less flattening and has a longer lifespan compared to most whetstones.

For premium stability and professional results, consider adding a Shapton Stone holder to your sharpening setup.

Pattern and roughness appropriate but still need to test
I haven't had a flat tire yet, so I also haven't had occasion to test these but they seem like great value for an extremely low price (especially versus a new tire.) I have handled them to try and gauge how quickly they'd smooth a hole, and they're rough / sharp and aggressive enough that I expect them to work quickly and well on not only tires, but on a variety of other materials. This pattern in particular should allow material to be shed and then passed backward pretty easily without clogging things up or slowing them down. If you've bothered to buy a patch kit for your tires, you really ought to have one of these around.

Great value, easy to use, and do a great job.
Great for tire repair! It fits in any drill in a snap, so you are able to ream the hole out in a tire so you can patch and repair the tire. My shop used these all the time, and never had any issues with them. They hold up well, and do the trick for just about any size hole in a tire. Great buy!
