I saw the grovel tool and the show, and thought about other inventors that have done great work out there.

In general, like the inventor of the grovel said, I had 40lb's and wanted to drop it to 5-10lbs. For those whom have carried a rifle while hunting, nows a 10lb rifle can be tiresome after a mile. I praise the grovel inventor. Other great inventions that I've ran across in the last few years are:

1. The waterbob (tub water bladder) Although its pricey due to the increased hype of preppers now for a pound of plastic.
2. Survival burial tubes for storage.
3. Gamma buckets and lids.

Its a small sad list though, most of the good stuff has already been invented and marketed for the military though.
