  • Publication number: 20070111636
    Abstract: This application is for 4 complimentary weapons embodying an arsenal for safely practicing medieval battle skills against an opponent: (1) A lightweight foam covered sword for single handed or younger child usage, (2) A heavier foam covered broad sword for two handed use, (3) A foam covered throwing spear and (4) A higher density foam protective shield To ensure users are not injured during battle the structural PVC pipe used for the light sword, broad sword and spear shafts is covered with a thick 1.25? to 2? layer of lightweight, closed cell polyethylene foam tubing which has excellent tear, tensile, and resiliency to abuse. To strengthen the handle, improve handling, and prevent the foam tubing from sliding back on the sword handles during intense use, the handles have a second larger diameter pipe heat fitted (or otherwise bonded) overtop. The tip of each weapons shaft is safely recessed within the protective foam and covered with a blunt PVC cap.
