This weekend went to REI looking for a new trowel, for my upcoming section hike, this is what I bought, just under $3
It is a snow stake, does a quick job of digging, weighs next to nothing ( online specs say 1 oz.), and doubles as one of my tent stakes.
I would say it is about 1-1.25 inches wide, and about 9-10 inches long.
thought I would share.
