Tin openers

I have one from that Swedish shop, which, like most Swedish can openers, open them from the top. The real benefit of that is that there's no shart edges on the tin - it just pops up the circular lid from inside the top, if that makes sense.

I never understood why you guys cut off the top edge of the tin here lol

Mine are like that Sarriss they bought from the local hardware shop just basic metal ones,  a couple in the house then one for camping they seem to work well enough.
