black and silver bars are winch bars for tightening straps on a flatbed trailer, also used for locking down chain binders, notice the extra bracket on the end of the black one...thats for holding the handle of the binder, the chrome one is just hollow and you can slide the bar over the handle of the binder to close it but if it slips out of your hands while you are straining to tighten the binder it may flip through the air a hundred feet or so...hence the nickname 'widowmaker'...I've seen a few bars go sailing but fortunately they didnt hit anything other than the ground...
I don't know anything about the hatchet other than its basically a piece of crap...my guess is that it was at one time part of a "camping gear package" deal at a department store back in the 70's...but its really too flimsy to actually be of any use in the woods...it could also have been meant for throwing...I don't know, but thats what I mostly do with it..
four way tire iron, 3 sizes lug wrench and pry bar to remove hubcap...I honestly cannot remember the last time I took a tire off of a car, has to be a decade at least...I always put a dab of grease or never-seize on the lug and never had any trouble taking them off again later...
just above the winch bars is a pin puller, for unlatching kingpin from the fifth wheel when disconnecting trailer from tractor..
lower right is a couple of real old spud wrenches, don't know their origin either but would guess a sawmill..
