Honoson 6 Pcs Diamond Sharpening Hones Sets Color Coded Diamond Sharpening Stones Tools Flat Hand File Knife Set for Hunting, Outdoor

Bought these to sharpen router bits. Work great

These aren't really a bad product - they just used a bad plastic. The plastic is too hard/brittle to do anything but light rubbing or scrubbing with it.I've only had them a couple of weeks and use them a few times and done of the handles snapped

Están buenos, pero deberían ser un poco más largos de la parte de la punta diamante

My 12 year old mandoline blade was not cutting like it should, and it needed to be sharpened. I didn't want to have to send it somewhere to get it done, and I also didn't want to take it apart to get to the blade. I found a YouTube video that showed a chef using these sharpening stones to sharpen his mandoline, so I bought some to try it. They arrived the next day, and were very easy to use. The handles on the stones make it really easy to get to the blade and keep your fingers from getting cut. Just a few passes over the blade, and it was just like new. It blasted through the carrots I cut with it with no problem. I am very happy with this purchase.

Works

These will sharpen a dull blade fairly quickly, Just don’t expect them to last very long (obviously depending on frequency of use and technique). All in all, not a particularly good investment unless you don’t sharpen your knives very often. They are best for small blade lengths.

These are good for touching up carbide tipped saw blade and other edges. Also for flattening things that a regular file isn't so good at. But, these should really be labeled with the grit#. Color coding is not universal or easy to remember.

I used these to dress brazed carbide lathe tools. They seem to work pretty good, even on carbide. And not to mention cheap which is nice.
