Do you have a freecycle website for your area? Post a pic and see if someone wants it, then they can come disassemble it.
Also, some use a cap to cover the actual fastener, and those usually just pop off (or gently pried off with a screwdriver).
I’m a bit confused, though. Channelocks are pliers (tongue-in-groove type), and if they wouldn’t do it, how would regular (slip-joint?) pliers help?
Good luck with it.
