first off i'll say that i have never done any trapping..
if i did for survival i would try and put some kind of
snare across a game trail..
as for the question i went to my copy of "deadfalls and snares" by A.R. Harding--1935..i think you can reprints from
the "fish,fur,game" trapping magazine..anyway--Mr Harding has
instructions for making about 60 traps from bear pits to
skunk traps..he either used or got the "how to do" from guys
who traped "back in the 80's"--and thats not 1980's..
he liked hand made traps because you could make them with a
Ax and knife and held that 6 well made and placed wood traps
would get better results than 50 steel traps set carelessly..
he was traping for the fur and needed the money so he was
just not fooling around-----
OK--now to the crux of the matter..HUMAN SCENT--
no where did he talk about wearing gloves or trying to hide
his scent when he HAND CRAFTED all those traps..
his concern was proper placement of the trap and the way
the trigger was made---you need a BIG heavy log for a dead
fall..and that figure "4" trigger has to be made just so..
so i would say it's craft and placement that will work and
not the "good luck charms"
