When we first produced our capo the screw did not have a cap on the end. It was just metal on metal. The Delrin cap was added a few years later. People began to inquire about them, but they didn’t know what to call them. So they’d make up their own descriptive names. Here are some of the names people have used to describe Delrin caps (all taken from emails, listed in the order received): capo nubbies bore-screw ends nose plugs capo savers groove prevention units nubs bumps miniature landing capsules boobies acorns nose cones little plastic bobbles rubber capo boots rubber tits weird little round space pods rubber bullets dreidels hard nipples little coneheads
