Best nail file for dry cut tapering

Hi all, I was searching Amazon for a metal nail file to file down my .5mg klonopin pills to the desired weight for my taper.  There were lots!  Can someone recommend a good, metal nail file that will not add fine, nail file particles to the pill or the part of the pill that is filed off?  In other words, when I get to really low doses and start filling capsules with the klonopin that was filed off, I want to be sure the container is not half klonopin and half nail file particles.

I personally use a metal file.  It works great, can be rinsed.  Emery board not a preference, for me.  

Is there a thread on the best ways to file down pills? I think I may need to do something like that soon.

I've never seen a thread on "How to File Down Pills", but it's pretty easy. 

 

You might need a scale, like the Gemini-20 on Amazon, to make sure you're getting the dose you want.  Many many BB here have done the same thing as part of their taper.

I bought a cheap metal file and I didn't like it. I bought a more expensive one and it works much better. the one I got is: Revlon Salon Pro Nail File, Sapphire Coated Filer Made with Corrosion Resistant Stainless Steel, for Natural and Acrylic Nails
