Welcome to Laser Cutting
Well done, as doing is hard and explaining much harder. I only comment to assure that saw blades do indeed make good knives, in fact near my home in Cincinnati, there once a place called the , Ohio Knife Company. The founder used old bandsaw blades from lumber companies as a cheap source of metal, and built a million dollar company.
I made one it looked neat, but there is one problem, the plastic parts lack strength. Third flight with APM controler GPS and FPV gear she hovered nicely , it was landing that was her undoing ...landed on an uneven spot only a 2 inch dip but the rear hit first. ripping the internal frame free of the outer case.... ... tried a quick repair and on the fourth flight broke the front mounts .... fly it without external case ugly but flies well enough not my first crash but it was a bit aggravating , still I have been crashing flying things for 50 years
