CBRIGHTCBRIGHT Sharpening Stone Set, 6pcs 3000# Ruby Whetstone Kit Small Fine Polishing Sharpener Stone for Sharpen Chisel Gouge,Knife and Bladed Cutting Tools, Variety of Shapes[Length:100mm(3.94Inch)]

For the price of any Ruby stones these come in fairly inexpensive. I have used these to break edges on quite a few metal projects and they work great. I keep them soaking in a light oil. I would purchase these again if I had too. The container they are in took about a five foot fall and none of them broke, which surprised me.

Nice stones, having a couple of different grit in the set is useful.

Great packaging came in a spongy case, only one stone has minor imperfection we'll see when we use it.

These are fantastic little stones for the price. I total of 4 stars because they have chips and could be better. The 3000 grit is quite smooth but there is a grain to how they have been shaped. This is an imperfection but it’s kinda nice to change direction of the strokes to remove more metal. Yet if I was smoothing something critical you would want better stones.

These stones do not wear away like other stones. reminds me of a fine ceramic stone. They are very fine stones so are more for polishing type applications. They don't remove allot of material but with that said they cut fast for such a fine stone. Good for honing the edge of a blade or smoothing a sharp corner on a machined part and tons of other things around the shop. These stone will likely last a lifetime. When they get loaded, it seems similar cleaning tricks for ceramic stones work for these as well.

These work great for getting into and around small metal areas that need a fine edge removed or something smoothed. I accidentally dropped the largest stone from a height of 3 feet onto a concrete floor and surprisingly it did not break.

I was going by the picture but it is very deceiving , these are so small they are hard to use.Not as big as a pencil.

I use Ruby stones daily at work for the past 40 years. The quality seems to be as good as the much more expensive stones I bought from geiswenn$. Just a 5/16 wide triangle stone from geiswenn is $118. I will be buying more sizes from Amazon
