The few things I never leave at home are my.
S.O.G multi-tool - It was an E-bay buy "used" $30, been backing it for 5 years now no issues.
M16-13ZM - Spear Point - Designed by Kit Carson, $60 Rock solid knife for the money, No complaints other than I had to lock-tite the 3 pocket clip screws they kept backing out, but the clip screws on my sunday knife "benchmade stryker" done the same thing.
Walther P-22, .22 long rifle pistol great little carry gun for back-backing , or going to wal-mart. Its light, extremely accurate, and reliable with most brands of ammo.
And don't laugh but my Gerber Gator machete $30, I have used and abused it backbacking, truck camping, on the farm, on large brushfires, and during an Ice storm. if it needs to be sharpened i hit it on the grinder or with a chainsaw file in the field. I've used the saw building camp items, and have used it more like an ax than a machete. Only issue I've had with it is the handle got loose about year 3 and i had to tighten it back up.
Thanks everyone that replies.
