A valuable lesson was learnt today
http://i.imgur.com/nTgLej8.jpgI have been feeling that my tension was way off lately, so I decided to try something: I applied the bare minimum of tension I could (So light that the tension tool would eventually fall off if I ligtened it a little) and the lock opened effortlesly in no time.
I have been picking since 2009 and I have been GREATLY underestimating what 'light tension' meant and being a touchless brute all this time. Never too late to learn!
