When they came out in 2011, our Flagship Line was the first full tang weapon-grade line of swords. After the release of our Integral sword line, we spent 6 months gathering feedback from over 30 top sifus and improving the design. These swords are the result of that work. They are lighter, quicker, stronger, feel better, and trap better than the Integral swords, which were already the best swords on the market. The balance on these swords is second-to-none. In addition, the blade shapes have been modified to better suit multiple lineage's requirements.
