Locksport is just a alternative way to say, picking locks for fun. Its something Ive been into since I was about 12 or 13 and I found out I could pick the door locks at my school with a paper clip. You'd be surprised how easy it is to pick most locks you see every day.
There is an intense satisfaction from feeling the plug in a lock finally turn, indicating that you have opened it. Not to mention how cool it looks to pull off in front of someone. Makes you feel like james bond
My version of a fidget spinner is picking a padlock over and over.
Anyone looking for a new hobby that you can do almost everywhere, I suggest checking it out. You can buy in for about $15 or make a set of picks from the little steel strips you find in windshield washer blades.
Protip-- Don't buy a set with 10 or 20 different picks cause they are mostly useless. All you need is a pick, a rake and a few different sized tension wrenches.
