With a double weapon form developed, I began to adapt it to as many weapons as possible. In Bagua, famous double weapons were the Half Moon knives and deer antlers. The need was for a longer blade than most knives, but small enough to justify double weapon use. By purchasing two of these Tanto knives, I had a perfect double hand weapon that was much more discreet than the larger brass handled Butterfly Swords. The black scabbard does not draw attention, and they slip easily into a bag for carrying. The smaller and lighter size means adapting the chops of the Butterfly Swords to slashes with the Tanto, teaching how to change momentum and application to different styles of weapons. Cold Steel blade quality ensures a razor edge and blade strength to match the beautiful Japanese furnishings.
