What is "t-blades"

T-Blades are a type of hockey skate blade manufactured by the German company T-Blade . Unlike tradition skate blades, T-blades are replaced when worn out. The manufacturer of the T-Blade states that "Compared to conventional skate blades, the T-Blade runner lasts 4-5 times longer." The T-Blade is held to the skate chassis by a stabilizer and six screws which require a special three-pronged wrench. The blades are sold pre-sharpened. Jochen Hecht of the Buffalo Sabres, Dennis Seidenberg of the Boston Bruins, Marcel Goc of the Nashville Predators, and Christian Ehrhoff of the Buffalo Sabres are NHL players who use T-Blade skates.
