I just saw this ad in my March, 1982 issue of BICYCLING magazine. It's on page 155.

"Lo-El Surviv-All

If wilderness camping is your desire, the Lo-El Surviv-All may be the all-purpose tool for you. This one-pound, 15 inch long unit is a shovel, hatchet, fish scaler, saw, and nail puller. Underneath a screw-off plastic cap on the handle is a survival kit packed in a waterproof plastic tube including the following items: safety matches, knife, flashlight, needle, thread, can opener, safety pins, candle, hook with lone, adhesive bandages, iodine swab, and a small container of soothing lotion for insect bites.

The Lo-El Surviv_All retails for $17.95 and is available from Lo-El Enterprises, 706 East Main, Lake Mills, IA 50450. Replacement parts are available from the manufacturer."

With this tool Joerg wouldn't have to worry about finding loose nails to fix broken chains with. LOL
