Named after Mt. Jefferson and measuring just over 19mm, you can choose between solid Brass, Copper or Stainless Steel. This Top features a press fit Ceramic (Silicon Nitride) Contact Point. With practise you'll be getting spins between 4 and 6 minutes with the stainless typically spinning a little longer. Its small size and robustness makes it perfect for EDC.
This little giant comes with a knurled grip and weighs in at 31 grammes, with the stainless a touch lighter. The contact point is Ceramic, Ceramic (Silicon Nitride Si3N4) bearings are used for the longest and smoothest spin times! This is possible because they are virtually frictionless and lighter than Steel or Tungsten. In rare cases if dropped it is possible for them to shatter so some care is needed when selecting this contact point. They are also used in applications ranging from championship Tour de France cycling teams to the engines on the space shuttle!
