Former hockey star Wayne Gretzky is still keeping his hand in the game with the new “Therma-Blade.” Which is what, exactly? “Thermablade is designed to maintain a consistent temperature of approximately 5 degrees Celsius using a small battery and a microprocessor stored within each skate blade holder. The warm blade acts to increase the thickness of the water layer between the blade and the ice surface, dramatically reducing gliding friction and starting resistance for skaters.” Oh. We’ll have to take Gretzky’s word for it, because that stuff is WAAAY over our head. So’s the price: $399.99 a pair. We’ll stick with our sissified figure skates. It’s not like we’ll be hitting into any power plays anytime soon, anyhow. Details are at ThermaBlade.com/en.
