Move to try to get to know a woman these days, and half of 'em run screaming that you're stalking or harassing them...but they're usually the ones with non-human hair colors anyway, so no biggie.
A very stiff blade will work on soft metal like brass and aluminum.
For harder metals, you'll need wee nippers with hardened jaws, and a very fine diamond file to remove nibs on hard material.
Found a reference link, and found that most of my kits that had these things have already moved West.
Also found one, all I need, in the old Lindberg-boxing of the AMT '34 Ford pickup.
