Mine is just my first name and the first two letters of my last name. The avatar is a Halligan. I work for the fire dept and a halligan is an old school fireman’s tool still very much in use today. It’s for forcible entry, that is, opening things that don’t want to be opened. I’ve carried mine on every shift for almost 20 years, and can confirm there isn’t much I can’t open with it. 

Ryan/// ~sigh~ I blew up another bowl. Moke told me "I made the inside bigger than the outside".
