Review: Long lasting quality. - Used in conjuction with a "course" grit sharpener, this fine grit sharpener brings my carpenter chisels and wood planes to a like-new, razor sharp edge, giving years of service and high quality mortise and other wood shaping projects. I have used this brand for years and cannot wear it out!
Review: Brilliant Product - I work for a big grocery retail store. I work as a butcher and we are not allowed to have any outside sharpeners in the meat room. I found these and bought two different ones. They dont look like a knife sharpener and I can keep them on my belt loop without anyone knowing what they are. They work awesome for the long days when I was fighting to keep my knives sharp with cheap means. Worth every penny

### ⭐⭐⭐⭐ Four stars
*by B***. on December 16, 2014*

I've always been fascinated with sharpening a knife, I think every real man has been, it's in our dna at birth to be drawn towards sharp dangerous things, and things that go boom. I've attempted to obtain razor edges on every knife I've owned, Arkansas stone, the big set that comes with rods and clamps, the infamous sharpening steel that your butcher makes look way too easy, with a bad ass sound that you'd love to make. That sound is great until you dull every knife in the house not knowing what you're doing. I've owned them all and still have a majority of them, even after 30 years of attempting to have every blade around me sharp enough to shave the family pet, I still can't get it the correct angle and end up with a very sharp blade, but not the razor edge I've always wanted. The dmt "red fine" sharpener is another one of my attempts to find that magical sharpener that'll achieve what I desire, but no sharpener will ever do that, this is a tool, it's only as good as the hands behind it. It's a fine grit sharpener but you won't know exactly how fine until you drag a blade across it, in my opinion this should be considered a medium grit sharpener. They have course, ex course, fine, ex fine, ex ex fine, why not a medium? Who knows, but this is well built and hopefully will survive on my key chain, seeing how much our keys get thrown around. I only gave it four stars because the two plastic nipples that hold it open and closed, seem under built or rather could improve upon. The sharpener is cheap enough so I think I'll get an extra fine for a more finishing edge. Time will tell how it holds up, if it breaks it'll still serve as a good sharpener for the drawer as long as it isn't lost if it blows apart somewhere unnoticed. I ordered this along with a rat 1 g10 folder and it would shave my arm, so I'd say from my own opinion that this would be great for getting a blade back in shape and then using a finer grit for finishing, great buy and nothing but super service as usual for amazon!
