This is a quick project I made casting aluminum Key fob. I made a small flask and a pattern from MDF. After a bit of metal filing and cleaning it looked really cool. The Key Fob could be carried in the pocket and even be used in case of emergency for self defence or for emergency car window exit ;-). I also combined a bit of paracord for this project the Snake stitch guide can be found in my Paracord Projects blog.
Some late addtion threaded adge to give it more interesting look.
