Amtech – Double Sided Folding Diamond File, Durable Plastic Construction, Comfortable Handling, DIY & Trade Use

Great product for the cost, folds up so out the way in our knife draw. Packaged well. Arrived on time

It sharpens! The file grades are quite coarse, so its definitely for sharpening and not honing. I wouldn't use it on my best knives, but it will do for what I need it to do.

Excellent diamond file. Do use diamond cards but grip is becoming a tad awkward. This has proved ideal

Good value for money nice size good for storage good quality and grip and versatility and good portability

Used it once, worked OK. Tried again when one side of the sharpener fell out. Had to glue it back in

The 'butterfly' design is very tidy and unlike some reviewers I have no problem with plastic so long as it's the right plastic. This is guesswork but from the finish and behaviour the black folding casings are some kind of fibre-reinforced material a couple of millimetres thick, giving slightly and recovering if (gently) squeezed, while the red 'blade' is 5mm thick and appears to be a slightly resilient formulation of industrial nylon. If I'm right (big if) both are reasonable selections since all they have to do is protect and present a couple of diamond-coated stainless steel slips that are the working surfaces. On my example both were dead flat and immovably attached on receipt and they are still in that condition after testing on scrap steel and dulling the razor-sharp corner of some damaged glass. (After use I routinely clean diamond-coated tools under running water and to my eye there was no sign clogging or 'bald patches'. The unusually coarse texture probably helps with both.) A pleasant surprise was that the fit is such the thing unfolds easily but stays open, and when used as a file if grasped firmly with one hand while guiding the tip with thumb and forefinger it is very easy to file with the whole length and width of both diamond surfaces so long as the strokes are light and steady. While I seriously doubt it will outperform the sort of hideously expensive pocket tools raved about on YouTube it works, nothing has broken, loosened or failed to perform the limited sort of tasks I expect might arise in a suburban environment short of a zombie apocalypse... PS If, as other reviewers have stated, the rivets do failbreak I'll probably replace them with a couple of 'Chicago' screws from the oddments bin a highly recommended standby no one seems to have heard about that these days are almost impossible to find in any physical outlet but are easily ordered on-line, post-free, from China... alternatively I might thread some cord through the holes and use the business end thing as a key fob for the garden shed. Try doing *that* with a Lanksy Puck, not that you'd want to at thirty dollars for two, plus international shipping!

Yep, a Tortoise! Ours is the small type and her beak does get a bit long and trying with a nail file does not work well, I need to be quick, for her and my fingers! This is rough and it is diamonds so gets the job done quick and does not hurt her bottom lip, perfect!

I already have one of those sharpeners that you pull though a V groove. Not only does it not work very well and takes the point off the end of the knife it makes an awful spine chilling noise. I also have an oil stone but its a pain to use. Not only does this sharpen knives quickly and easily it also sharpens the blades on my food processor and electric vegetable chopper. You do need to be careful when sharpening especially both sides of a knife and would recommend a protective glove or run the knive over the sharpener. Apparently American and European knives are sharpened to an angle of 20 deg and Asian blades 15 deg. With this you will have to guess the angle but I finish with a ceramic steel that finishes to razor sharp.

As advertised; good quality

Produit pour utilisation très occasionnelle, fait juste le job. Durabilité et qualité pour le moins douteuse, mais, comme souvent, en relation avec le prix et la provenance.
