Medieval and Renaissance Daggers. Our daggers can be divided into daggers intended for fencing, which are dull and made from quality tempered spring steel: the same kind that’s used for sword blades. The other type is costume daggers (which are usually sharp or at least have a sharp point). These daggers are meant for collectors to display or as an accessory for a costume. You can order a leather sheath for your dagger, and some can be embellished with etching or engraving to customise them.
