Blue Spot Tools Diamond Sharpening Whetstone Set, 3-Piece (Extra Fine, Fine, Coarse Grit, 6 x 2-Inch, Blue)

I used these to sharpen wood chisels together using a Stanley jig with the stone lying on a very flat granite surface. The product cuts easily and quickly to achieve sharp edges. The course stone is helpful to quickly remove metal for damaged or chipped chisels to get down to desired angle. The finer stones are good for finishing the job. The diamond surface wears down to an extent with use so the initial grading becomes finer than the stated fineness. However, I can easily live with that. The grinding surface is on quite a thin plate and I suspect that can be tricky and lead to uneven results unless placed firmly on a very flat and solid surface. Again, I used a solid and flate surface with success and I am pleased with the product. I prefer these to a wet stone.

Good for the price. There are few points which could be improved. They are small and slide a lot during sharpening, you will need to fix them on a board or come up with another idea. Also using glass cleaner (glass, not window cleaner !!!) instead of water will improve results. I sharpened knives a chisels, both worked well. You may not get an extra sharp edge with these plates, some stropping or a finer stone advised. Overall they are fine for kitchen knives but i would get something better for tools or expensive knives.

I bought these to sharpen some old chisels.I've only ever used whetstones before, these worked just as good. In fact for the price I was really impressed, their is no grading numbers for the stones just coarse, medium and fine. One chisel had a couple of nicks on the blade so needed some serious filing and it came up a treat. For home or infrequent use these can't be beaten.

It sharpens very well and fast, however I will remove one star because it is too small, which makes it very difficult to sharpen large knives or small swords on a table and one star for the super slippery plastic bottom, which means you have to nail it or somehow confine it on the table in order to sharpen at all.

I used Draper spray adhesive to glue these to a wooden board for ease of use when sharpening chisels and plane blades.The coarse and medium grades are actually quite coarse and rarely used. The fine one gets the most day to day use.They are reasonably flat, although one of the plates was bent and pulled away from the plastic backing when it arrived. I put a bit of super glue in and held tightly in a vice to hold it straight and now it's fine.They are not as flat as sandpaper glued to glass or an expensive diamond sharpening stone (by the likes of DMT or EZE Lap) but they are quite flat and do a good enough job for the price.The holes in the plate can make sharpening very narrow blades quite difficult but for the price it's a great starter set.These are good as a cheap stepping stone towards a full set of more expensive stones.

This set of sharpening "stones" is really good value for money. After having browsed around for sharpening stones that I can use to sharpen/hone my chisels and my plane irons, the choice seemed to be either spending a small fortune buying individual stones of more or less exotic character and price, or give this set a go.In order to get the best results with this set I glued the plastic side of the stones to a scrap granite tile. This ensures a flat grinding surface and stops the stones from sliding around on your workbench. Initially I thought that the stones were all a bit on the rough side, not really matching the "coarse, fine, and extra fine" description, but after sharpening a set of 6 chisels the roughness has worn down to fit my expectations. I was then thinking that I had already worn the stones out, but that was not the case. I have just re-established a 25 degree bevel on my 1 inch chisel (that had a 30 degree bevel so a lot of material had to be taken off), and the coarse stone did that just fine in less than 5 minutes.Not knowing what the grit of each stone is can be an issue, but as the grit of a diamond stone will always wear down gradually, and the abrasive value deteriorates accordingly, it seems not to be a too big issue for me. After having taken the initial roughness out of my set of stones I am guessing that the grits will be somewhere in the area of 200 for the coarse, 400 for the fine, and 800 for the extra fine, but that's just a guess.A set of expensive diamond stones might very well last a lot longer, and be of better overall quality, but for my requirements this set works perfectly and can be replaced at a fraction of what an expensive set costs.NB! A lot of people have been complaining that the colour coded plastic part and the "stone" come apart with use, but I have been spraying mine with loads of water, and worked them quite hard as well, without this happening so far.

Not the best quality diamond sharpening stones you can buy as they do wear out quickly but they do sharpen my chisels well with just a little bit of water (or spit if more convenient) to help lubricate it. for the price I was not expecting much but they did better than expected.

evan though these are about the cheapest (in price and quality) version of a diamond set you can get....do not let that put you off, these are flat, evenly surfaced and when mounted to a flat board to keep them that way will last a long time.There is no ultrafine grit here so to add to this get yourself a separate 1000 grit + or honing strop for final finishing and youll be set to sharpen knives or tools for years. I have a set for me and i brought a set for dad for xmas...both happy and would/will buy again when needed

Rapporto qualità/prezzo davvero ottimo. Consentono di affilare rapidamente, e le dimensioni e il peso ne permettono tranquillamente un uso "sul campo". Avvertimento per chi non ha pratica di affilatura: bisogna imparare ad usarle, e considerare che le diamantate sono piuttosto "aggressive", e sarebbe meglio farne un uso non troppo frequente. La qualità dell'affilatura dipende molto dall'abilità dell'utente.
