Coarse

This file will shred the thickest nail easily. By far the best toenail file I've had. I've had it for years, I just wash with soap and water and it looks brand new.

I have thick toe nails that I have a hard time managing. This file is coarse enough to remove lots of material quickly, flexible enough to be able to follow contours, and it's easy to clean. This file allows me to take control of my unruly nails, greatly reduces socks snagging on them, and in general just makes them look better. I even use this file to knock off the sharp edges of my dog's nails when I use the trimmer on them. It's actually a bit too flexible for dog nails, but works in a pinch.It's the most expensive nail file you'll never regret buying.

This flexible diamond file whittled down my toenails, which were like little horns, like magic. Nothing has ever been this effective. I love how flexible it is at the corners of my toenails to avoid ingrown toenails. No more ripped socks now! No toe contact inside my shoes anymore, making more room and comfort. Expensive, yes, but it WORKS!

My wife bought this one few years back, it worked great! It is aggressive with the corse diamond texture, super easy to file down the nail. She uses a lot so it got pretty beat down so we are ready to get a new one. We ordered again this one again in April 2023. The quality has been drop so much. It has no major difference than the $8-10 ones. In addition the brand new one is so much weaker than the beat up old one we got few years back. Won’t come back to get the low quality product for high price! Not worth it!

Worth every penny. Wish I'd bought one of these when I was about 18 because I'd still be using it and I'm 64 now.A couple minutes every couple days and I don't even need nail clippers.

The file is well-made and the abrasive surface is very reliable and uniform. However:1. The abrasive doesn't go all the way to the edge.2. The abrasive is only on one side.3. The body is very flexible (much less stiff than, say, a Diamon Deb file).

I am not the sort of guy who usually spends this kind of money on a nail file, but I took a chance. After using it for a few months, I've decided that it's worth the money. I snowboard, ski, hike and bike. I've also had toenail fungus to varying degrees for most of my adult life. Thick, uneven nails like mine can cause a lot of problems when paired with snug-fitting boots and shoes. The best way to deal with it is to keep the nails cut short and to file them down so they're even (not lumpy) -- so they don't catch or rub on anything. This file does a better job at that task than anything I have ever found before -- a massive improvement over any nail file or emory board I have been able to buy locally. If it were a little less expensive, I'd give it 5 stars. It is definitely a coarse file, and I wouldn't use it on my fingernails or on my normal (non-infected) toenails.

I bought this file as a gift for my husband, who is constantly wrestling with his toenails! It's everything it claims to be - it's coarse, high quality, and perfect for tough nail "jobs". I'm very happy with my purchase!
