Sproing!

What is this thing? Is it an ollie trainer, or is it just a regular ole Maui and Sons skateboard that some eccentric nut decided to make even more dangerous by replacing the trucks with giant springs? I’m not sure what you could actually do with this, besides try to sell it on Ebay. This appears to be the “Thrasher Sharkson” pro model.

Thanks to Matthijs for the tip.
