I made a pair of log dogs for my dad for $10 worth of rebar. These can cost around $50, so they were well worth the time.
The process was really simple. Heat the rebar til pliable, and bend it in a vice. Re-heat, and quench in oil.
I thought this was cool, and my dad was super happy with them.
(I'd make and sell them if anyone was interested :) )
