Fast Brass was designed to reduce the effort of installing brass speed knocks and help ensure a tight holding pressure on the string. Its patent pending design allows for the knocks to be installed with up to 4X less crimping force compared to other designs while tightly holding to the string. They are swiss screw machined to tight tolerances. The size and weights of the knocks have extreme consistency.
