One thing I want to mention is when using these wheels is the necessity of using eye protection and a dust mask. Often, small pieces of the wire break off. They usually end up in your hands, but I have actually had to pick pieces out of my fore head.

Besides wearing protection, you should always have tweezers, a needle, and a source of magnification handy to get them right away, before they go deeper into your skin and cause infection.

I prefer wood to plastic, leather to nylon, waxed cotton to Gore-Tex, and split bamboo to graphite.
