I own the Gerber NSN folding shovel and the Glock folding shovel. IMHO, the Glock wins only because it has a saw in the handle. If we were just judging the tool as a shovel, I would say the Gerber would win. The Gerber is heavier, but Grunt-proof. Also, the saw in the Glock shovel's handle cuts fast and clean.

I have been meaning to pick up a couple of the Cold Steel reproduction WWII style E-tools with the small wooden handle.
