EdgePoint Diamond Sharpening Cards (3-Pack) | Credit Card Sized and Color Coded | #300, 600 and #1200 Grits | Sharpen Router Bits, Survival Knives and Tweezers.

Update: The picture below is how it came out of a very wet Prime padded envelope. No clue why it was not left in my mailbox, plenty big enough to hold it. Anyhow......I looked in the envelope further and found that the third card was separate from the package. No reason it would have fallen out but since the envelope was wet, it had stuck to the inside and had not dumped out with the main package.When I received package the three card kit was only 2 cards. 300 and 1000. What happened to the 600? Very disappointed.

These sharpening stones are convenient and perfect for taking with you “on-the-go” anywhere as they are an effective way to bring life back to a “dull tool”. The stones are awesome for kitchen knives as well as I definitely saw a difference when I sharpened a kitchen knife and proceeded to slice a tougher loaf of bread (Sliced rather nicely). They even worked on a small pair of scissors. Buying a set for both your kitchen and wallet/purse/vehicle would be a good idea.I like the convenient, little plastic sleeves/protectors they come in and they fit perfectly in my wallet.The material is solid and good quality so they should last for a good while. The three stones are great as they work well for each job they are used for. Don’t expect these to do really heavy-duty work though because they really were intended to be used effectively for smaller indoor and outdoor tools. I’d recommend these to anyone looking for a fair priced, quality set of sharpening stones!

I have used this product before and have carried these in my wallet for years. Had I not lost the wallet with the product in it, I would still be using the sharpener I have had for over ten years. This is an excellent survival assist; we often get the high performance knife then forget the sharpener. Not possible in this case- I keep 2 in my wallet which takes up no space and one is attached to my bug out bag. The ones I recently got now have a hole that allows one to attach to anything. The difference in grit allows for sharpening of severely dull edges but also more fine tuning of the blade. If you use a knife a lot or EDC having an EDC sharpener is a must. I also place these behind my credit cards which acts as a Faraday Cage

I used it to sharpen my knife. It did a pretty good job but didn’t seem to be great.

I purchased these diamond sharpening stones to use primarily in the kitchen. No one likes a dull knife. When I first received these stones I had no idea how they would be packaged. I was pleasantly surprised when I saw the 3 credit card sized sharpeners came in a holder. You can even hang them neatly in your kitchen when you are done thanks to the reinforced hole at the top! The back of the kit has directions, which is great for those with little to no experience sharpening knives. The products themselves work just as they should! My knives were back to their normal selves with just a few smooth hand movements.

I purchased the diamond sharpening cards for the sole purpose of sharpening my router bits and they did as expected. The only reason I gave them a 4 star is the extra fine car wore out to fast along the edges after a couple of bits.

I tried these to avoid having to buy new carbide replacement tips for my lathe tools.was very impressed as to how easy it was to re sharpen my tools with very little effort or skills

I bought these because they are lightweight and portable. I carry one in my backpack for sharpening my camping knives during a long trip and the others are in my car for my fishing trips.
