Manually machined Tungsten and Titanium spinning top.
I've been trying to break the 15 minute barrier for years and finally did it. The key is Tungsten over an Titanium. Scroll down for the time lapse video.
Please be aware that there are many variables when it comes to spin times so will vary. You should be able to easily hit 10-13 minutes with this top and break 15 with practice.
Comes with our custom leather pouch for carrying.
