How do you cut thickened toenails?

[RKP5637]

15. I see a podiatrist every 2 months or so. He uses a grinder of sorts, something like a

dremel to reduce the thickness and then trims them, It's doesn't hurt at all, but it does vibrate quite a bit, it tickles the toes. I also have a nail cutter that's something like a side cutter used to cut heavy wire. I start at one edge and just trim a little at a time working my way across.

It's something like this.

PS: I have arthritis, so I guess that's why it's covered.
