Lionhearted bladeworks manufacture these high quality saps in South Africa, the core of these feature 1mm 1070 spring steel that runs from the base of the grip area all the way into the lead puck (the lead is cast directly onto the spring steel) for added stability and power. The core then gets glued and stitched into the beautiful outer layer of leather, finally we get to the 2cm wide leather strap that prevents your sap from flying out of your hand when things get rough. If taken care of these saps will serve you for many years.
The large saps weigh in at approximately 380g and the small saps weigh in at approximately 320g.
