About: Lyratron was founded in August of 2011 after four years of research into the development of gesture-based electronic musical instruments. Originally called Light Harp Industries (founded 2007), we continue ...

Modeled after the Fairbairn-Sykes Fighting Knife from World War II, this handy letter opener is actually quite rugged and capable as a general purpose utility knife. 

Build this if you like the aesthetic/ergonomics of this collectable war relic and you want a general purpose tool.  If, on the other hand, you just wanna go out and stab someone with an undetectable edged weapon, might I suggest sharpening a toothbrush on a rough patch of concrete.  That's a lot cheaper than blowing $3,000 on an industrial laser cutter (plus the time and materials costs of this project) just to fulfill your violent impulses...  :-P

INSTRUCTIONS:
* Cut from thick acrylic using 40 Watt+ carbon dioxide laser. 
* Sharpen blade with Dremel. 
* Wrap handle with tape or something. 
* Test on whatever gourd or melon is handy!  :D
