The Spartan Spinning Top by Felix Ure is a simple design that has been created to optimize spinning times.
Machined from solid brass it is fitted with a tungsten carbide tip and will achive spinning times in excess of 12 minutes. Felix states that closing in on 20 minutes is possible with practice.
The top measures 38mm in diameter and 33mm in height. It weighs 76g.
The brass is left unfinished to slowly patinate with use.
