The Original Dragon's Heart:   Made from a carefully selected polyamide-imide, the original dragon's heart has 12% graphite content, making it extremely fast. Its speed is surpassed only slightly by it's durability.  One of these can endure over 1000 hours play before the edges become less than ideal. This is the best selection for speed shredding players.  

Thickness:  2.5mm
