Polish Tokarev Ammo Cans

Use some needle nose pliers on the tab that is on the bottom right of the top box and roll it over on itself like a fruit roll up.

 

The first one I used a chisel and hammer too!

I pulled the tab with needle nose pliers to make the slit across, but the chisel along the sides made it a little easier to start pealing back the top of it. Used my hands and pulled it back after I got it going a couple of inches with the chisel. Took maybe 3 minutes to get it open.
