Review: Great Value For Money - 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.
Review: Good value - this set of diamond sharpening stones comes in 3 grades, coarse, medium and fine and are relatively inexpensive compared to the price of a good India stone. They are a bit short, making them slightly awkward if used in combination with a honing guide as you will have a limited run, but for hand sharpening and honing thery are good and will help keep a good edge to ground chisels and plane blades. I have fixed mine to some short lengths oo timber so I can hold them in a vice: keep well lubricated and cleaned and they are an efficent sharpening tool.

## Questions & Answers

**Q: The dimensions are stated as 25 x 22.5 x 3.5 cm. This doesn't look right to me. Could somebody please check? Thanks.**
A: The ones I bought measure the following 152mm long (15.2cm)  50mm (5cm) wide and 3mm thickness. The dimensions stated do not match the product advertised. Hope this helps. Great product though.
Kind regards

**Q: Can you use it for ceramic knife ?**
A: Not sure if this will help, the problem with sharpening ceramic knives is the ceramic blade is very brittle, if you apply too much pressure to the side of the blade it could easily snap. If you still want to try you will need a diamond sharpening stone with a hardness of at least 10. Hope this is of some help.

**Q: Should I use oil or water as a lubricant with this type of sharpening stone? If yes, which? Thanks.**
A: These stones can be used dry or with water. Using water helps remove small particles from the sharpening surface, and gives a smoother sharpening in my opinion. I use water with a few drops of window cleaner in a spray bottle, which seems to work just fine. Be aware that the metal surface that the diamond dust is attached to may rust a little when using water on it, so cleaning and drying the surface after use is a good idea. For the money I think this is a great and very useful little kit that I use for sharpening chisels and planer irons with really good results.

**Q: Can someone tell me what grit they are?  Thanks**
A: They don't have that information marked on them. Any reply would just be a guess. Sorry. If you need a specific grit then you probably need a better product. These are perforated sharpening 'plates' mounted on coloured plastic backing and are 'cheap 'n cheerful' rather than professional quality.

### ⭐⭐⭐⭐⭐ Good starter stones for the price
*by D***N on 23 October 2015*

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.
