Season 8, Episode 2: Death Down Under.
Jeremy gets a grouper on his line, but as he's handling it, the hook pierces his hand, and a stage hand has to come and cut him loose.
The MT is seen very briefly, and I cannot identify it. You will see a pair of scissors folded out of one handle, and outside accessible tools on the outer side of the other handle.
I doubt Jeremy has a cheap multitool, it would not be up to the job.
What do you think it is?
