All Feders blades shape are based on XV century Peter von Danzig treatise.

Sparring Weapons are hand forged and have hot folded punta, and thick edge. Blades are hardened to 48-50 HRC to endure long and heavy training. Pommels are hot peened. Crossguard has fish tail shape to stand heavy blows, which usualy bends other types of guards. 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.
