hey mate i used for the first time ever a pair of those gentle giants the other day, i had a call out and i went to get my hook out of the back of my landy (as i had a mate here and his car was parked behind mine so we were gunna take his) and the back door wouldnt open and i have a cargo barrier in is so couldnt reach over the back seat, anyway my mate is into snakes and had one of those tongs with him, so we headed out to the property to catch this snake. With a bit of poking around a shrub an eastern brown came shooting out of it and across the lawn, i gently grabbed him with the tongs as i dont like them at all and he went bloody mental. Thrashing around and biting the tongs, after i caught him i stuck my finger in the tongs and squeezed as hard as i could, they dont actually apply that much pressure to a slender snake but i think with all the thrashing around the snake does it is more than likely where all the damage occurs. I think a heavy bodied snake would suffer injuries in the tongs tho
