not feeling the reamer thoughts
any markings on it?
the color does look the company RIDGID tools
I was in the pipe biz for 30 years, never seen a tool like this
the fact the handle has space in the middle tells me that it may require a line, rope to tie off
almost looks like a net repair tool
Maybe it's just a tool for holding things down while you solder them?
I doubt that, but other than a mold for making triangular-shaped lead fishing weights....
