Inspired by http://www.thingiverse.com/thing:1008102
Unfortunately I keep breaking the teeth off in my pocket so I designed my own in solidworks with a swivel cover.
Thanks to http://www.thingiverse.com/Hagen_sr4 for the inspiration
Update 29/03/2016.
I have added a fine toothed version, the gap between the teeth is smaller but the width of the teeth has remained the same for strength.
