Had a moment last week, so we strolled the flea market. A woman had a pile of rusty tools "anything $1!" and so I dug through it and found those channel locks. Then, in conversation, she seemed like she didn't want to pack the stuff back up, so I managed to get the 2 chisel heads for free. So, 3 tools, $1. (scissors shown for color)
A bit of work later - like 20 minutes - and I've removed the rust and made a handle for the big 2" chisel head. I love rescuing old tools.
