Hi, thought I post here for picture.

This is for them tin can caps..
I was pondering for a better way, something to cut them open instead of
hacking, mangling & denting them up.

Went looking thru my tools and came across this gadget. It's a plumpers
tool,
called a tubing cutter.

Gave it a try and it works super great! No dents, no rough cuts, easy to
use.
Just wanted to share this with you if you didn't know already.

Ridgid tools make this one. _JD_
