I ran across what may be a useful and inexpensive trowelt for lightweight backpacking and camping. For only $1.49 at the local K-Mart, I picked up a garden trowel to throw into my ALICE pack that sits in my closet. This pack, as most people know, is the one that contains items for "no, I don't really need it immediately, but it COULD be useful when the zombies march down Main Street or for the next typhoon/tsunami/tornado..."
The garden trowel is made in China for Bond Manufacturing in California. It has a 6 inch scoop blade of black plastic resin, with some metric and SAE scales to show depth. It is black but has some red points on the handle that make it more visible. There is also a lanyard hole. It is lightweight and seems sturdy and comfortable to use. I have not yet used it. but I gave it to my wife for gardening (that will be real "torture testing").
I do not sell these, and I only want to point out useful gear that does not come from a wlderness camping or survival store. As a good American. though, I should think about adding $50 to price and coming out with a nifty marketing gimmick: Faiaoga signature series with sharpened edges (one sawtooth and one razor sharp for chopping), a built-in siren and GPS, Morse code engraved on the handle, and a photo of me in the Peace Corps planting a garden, Without the marketing hype, the tool should be a good one for latrine holes, trenches and so on.
