my tool shelf in the basement is somewhat like Blast's..
however--what i find i really use is a hammer..screwdrivers.
a small set of socket wrenches..hand saw..for electric work
i use a Leatherman tool..a power screwdriver comes in handy,
i never used one untill i started putting flatpack book cases
and such from Ikea together..a power drill and saw don't get
much use but come in handy if you really need them..a hammer
will pull nails so the only use my crowbar got was to rip out
the steel bathtub when i put in a hot tub---
if i were you i would look around a yard sales..i"ve walked
away with a lifetime supply of nuts--bolts--washers--nails
plus files--screwdrivers--all the tools that some granddad
had gathered over a lifetime..
