All Feders blades shape are based on XV century Peter von Danzig treatise.
Sparring Weapons are made from quality spring steel and have full punta, and thick edge. Blades are hardened to 48-50 HRC to endure long and heavy training. We give one year warranty on our blades. Pommels are hot peened Durable cord wrap on the grip is hard to cut during sparring.
My sparring weapons were used on biggest HEMA tournaments for the past few years (for example Swordfish 2011, Swordfish 2012, Swordfish 2013, Longpoint 2013) None were broken during competitions.
