<p>This is the Dual Arm Blade used by Alexia Harmon in the book The Defender. This blade is attached to the forearm and in the book is launches forward 8in in front of her hand when she thrusts forward. </p><p>The book is available on Amazon </p><p><a href="https://www.amazon.ca/Defender-Larissa-Soehn/dp/0228866030/ref=sr_1_1?crid=28KCR30FY3XEH&keywords=the+defender+larissa+soehn&qid=1640116876&sprefix=the+defender%2Caps%2C114&sr=8-1">https://www.amazon.ca/Defender-Larissa-Soehn/dp/0228866030/ref=sr_1_1?crid=28KCR30FY3XEH&keywords=the+defender+larissa+soehn&qid=1640116876&sprefix=the+defender%2Caps%2C114&sr=8-1</a></p><p> </p><p>This original design uses the Openbeam aluminum extrusion which I purchased at Solarbotics. I also used 2 elastic bands and 8 M3 nuts and 8 M3 bolts from the Openbeam system. I also used 2- 10mm bearings I had laying around as the weights inside the blade weight but you could use anything.</p><p>OpenBeam 210mm extrusion</p><p><a href="https://www.solarbotics.com/product/52608">https://www.solarbotics.com/product/52608</a></p><p>This version works well. I plan on making a PLA version to replace the aluminum beams… coming soon.</p><p>Notes: I used the color change feature on the file “Alexiabladebackweight” to add in the 3 10mm bearings as seen in the picture.</p><p> </p>
