Answer 1

Trimmers are basically two metal combs where one slides back and forth against the other. Hairs go between the teeth of the combs and are sheared off when the comb slides and the teeth change positions. The part of the trimmers that touches your skin is stationary and runs parallel to the skin. Anything that is to be cut needs to stand up from the skin and be thin enough to fit between the teeth of the combs.
