Unique manual shovel/tiller - GIF
I guess this is technically a manual hand tiller, and not a shovel? This would never work in Colorado; there's a very good reason why they're called the Rocky Mountains, and not the Easily-Shoveled Soft Dirt Mountains. Cool tool though, obviously homemade. Looks like it has some height adjustment, bicycle handlebars, well-placed spike on the bottom, plus three cutouts in the blade.
