ULTRAVIEW CONTOUR KNOB AND HELIX KNOB
top sniggering at the back. These are Cerakote-coated (a kind of ceramic) knobs to fit most compound thumb releases. The Contour Knob, with non-slip tight grooves and an “ergonomic dished contour”, is designed specifically for thumbs. The Helix Knob, a slightly better established accessory, has a handful of ridges designed to fit into your thumb knuckle crease and creat new reference points. Come in a variety of lovely soft colours.
