We felt the need to reimagine this most iconic cycling tool as an heirloom-quality piece of art. Great care has been taken in machining the piece using single-crystal diamond tools to achieve a perfect surface finish, while the final feel of the piece benefits from an investigation of over 20 different knurling styles and depths so that it feels just right in your hands as it provides a lifetime of useful enjoyment. This is a true tool that you will pass on to your children and they will pass on to theirs.
