Ok guys I need some help here. I'm going to the gun show this weekend at the Atlanta Expo Center and I'm probably gonna pick up a spam can of 54R. I've noticed when you buy online that if you get 2 cans they give you a free opener, problem is I don't have the money for 2 cans so I need another way to open this can. Do vendors sell can openers at the shows? Should I even worry about getting a can opener? If I can't get a can opener what's my next best option?
