this year i bought a new item from Cabelas called "THE FISH GRIP".
it's a cheaper version of the more expensive tool you've been discussing.
it' made out of high impact plastic with stainless hinge pins.
it's sort of like a "visegrip" for fish, squeeze to lock on and flip handle to release.
it's a bright orange, so you shouldn't lose it, it FLOATS and has a WRIST strap as well.
it way's only 5 oz.
the BEST thing about it is the price, $ 9.99

!!
it also has a notch in handle to attach a small scale to.
it's not the "precision" tool the other one is, but IMO it would do most any job that you would need on a trip.
if i works out like i think i'll note it in my may trip report
