I was adjusting the length of some foils (fencing weapons) to change them from a French grip to a Visconti grip. I was doing them by hand with a tiny a** hand saw at first. They took forever and looked like sh*t so I bought a dremel. They were done must faster and the final product was a better done job. Having the best tools for the work you're doing will always produce a final product. Just try roofing a house using a screwdriver for a hammer.
