Diamond Machining Technology (DMT) W7EFC Whetstone Mini Diamond Stone - Coarse / Fine / Extra-Fine - Set of 3

These diamond stones work well I use them to tune my ski edges the blue removed the burrs easly,the red puts a nice sharpness, and the green just makes the edge a bit sharper and leaves a nice shine on the edges and of course that's after using a file.i can definetly feel the difference on the hill.i will not hesitate to purchase these again.

DMT is a great brand and I was happy to find these for the price. To me they are a good value but IF YOU ARE NEW TO SHARPENING KEEP READING. These are small, as is accurately stated in the product description. I bought them to keep in a tool box for touching up chisels and the like. They work great for that. I also bought a full size sharpening block to keep in the kitchen for my knives. The DMT set is great and will last for years bur is best for things smaller than a pocket knife This set is a great choice for many jobs and I recommend it, but it isn't for every job. Be safe and buy kitchen tools for the kitchen and shop tools for the toolbox.

These are a must have sharpeners. They're portable, very light and quality. Different grading, there's fine, coarse and finer. It's safe to use. Works really well. Sharpens your knives fast,efficiently and effectively.

OK, so, first off, like the headline says, these are really small. Yeah, I know the size is listed in the ad, which is why I'm not docking stars for that, I'm just warning you. You'll think, "Oh, that's OK, I can work with that." Trust, me, they're really really small. :D The trick I've found is to take some non-skid material (I'm using a little square of foam drawer liner stuff) and put the stone on that, near the edge of a flat surface (because they're really thin, too, so you need to be able to hang the handle of the knife off the edge) and use it that way. Once you get the hang of it, they're really effective. They took my work knife from it's beat up "cutting wires, slicing plastic wire loom, scraping gaskets, generally not being very nice to it" former state back to a nice, polished, sharp edge in about ten minutes. But man, unless you know the trick of it, they can be tricky to use. I also dislike the fact that the stone grades aren't marked on the back, but I solved that with a sharpie, so, it's not really worth complaining about too hard, I don't suppose. Overall, they're a great deal if you need a bunch of different grades of stone for not very much money, but... yeah, they take some getting used to.

These are limited use stones. They are great for packing in a go pack or a back pack where keeping the weight low is a priority but functionality is critical. They work well but they are short so they require great care in using them to prevent cutting yourself while using, especially in the bush where even small injuries can be critical. They do work well in removing material from the blade and preparing it for finishing stones to hone later or for a quick field sharpening when you must resort to using less than a razor sharp edge out of necessity. They are good for what they are made for you just must accept their limitations right up front. All in all, they are a great product. Just understand what they are really made for before investing in them. If you want a razor sharp edge, these are only the beginning of what it takes to get you there.

Used these to hone my jointer blades by wrapping parchment paper around 3/4 of one and then running the stone along the blade at its highest point from the in-feed table side a few times. It has never been sharper. Perfect size and easy to use.

I like the and they are very handy and convenient.

Die Diamant Schleifsteine passen perfekt in den bekannten DMT Schleifen.

I sharpen skates with a Sparks sharpener and use these stones to deburr the skates afterward. They are the perfect size and very comfortable to hold. I mostly use the blue one, finish with the green one, and keep the red one in my hockey bag for pre-game touch-ups. These stones have become an essential part of my skate maintenance routine.

Ideales para poner en marcha un filo que esté ligeramente dañado o embotado y rematarlo. Luego se puede pasar por el cuero para acabar de pulir las rebabas A la hora de afilar uso limpiacristales o agua y siempre con pasadas muy, muy suaves porque comen un montón, sino en cuatro días se quedan lisas como un espejo. Para limpiarlas uso una goma de borrar normal del cole Tengo otra de esta marca de dos granos, le he dado mucho trote, con ella he aplanado varias piedras naturales, un par de chinas y dos cerámicas, he afilado una navaja en acero carbono D2 y aún sigue comiendo bastante. El truco es lo que he dicho, apenas hacer presión y que vaya comiendo material, se marca el filo con un rotulador permanente negro y se va viendo como va quedando..tenía una navaja Timberwolf D2 mellada en dos sitios y usándolas por fases y luego puliéndola en cuero con pasta ahora vuelve a cortar el papel de tiquet de hipermercado Al principio necesitan un tiempo de rodaje, porque al principio vienen muy ásperas, luego con el uso se van desgastando algo y el acabado es más fino (menos rebaba), asi que si al principio los resultados son algo bastos...sigan usándolas. Al revés que con las otras piedras, cuando llegan al final de su vida y se ha desgastado del todo el abrasivo se acabó, pero bien cuidadas pueden durar mucho tiempo

Only got 2 of 3 stones as many others. How hard is it to send a complete set?

Needs patience to get the result you desire. Handy for home use.
