First off I have my set of Stanley screwdrivers. I use these a lot more than one would think but since they're all kinds of sizes including really small regular and philips drivers, I find myself using them to pry lots of stuff off of boards or shim something temporarily. A good set of small screwdrivers come in really handy on the bench.
Next, my pliers. From left to right: a pair of cheap edge cutters, a wire stripper, and a Letherman. The edge cutters I think I just got at Radio Shack but a high quality pair with a very strong cutting edge is essential for kit builders. This pair has been worn quite a bit and the cutting edges are nicked up. I'm due for a new set. I'll skip the wire strippers for now and go to the Letherman. This one I got from my Dad ages ago probably when I was still in Boy Scouts. It's your typical multi-tool with all the fixings but I mostly use them for the needle nose pliers and for the straight edge knife. Of course a separate needle nose plier would be OK but I had this on hand so I use it. The knife gets all kinds of use from cutting rope to stripping coax. Again, this particular tool is getting a bit long in the tooth and deserves a retirement. Always keep in mind, a very sharp knife is safer than a dull one! As promised, to the wire strippers. I got this particular one at a garage sale in Indiana, but I think you can still find them at the hardware store. It is really great for chopping off coax in one cut (see the cutting edges below the head) and quickly stripping small hookup wire. It does not fare too well with stripping coax and when you get too small of wires in there, it just eats them up. It does, however save a ton of time so I use it when I can.
So that pretty much covers all of the stuff I use the most. There's lots of other stuff I use too but much less frequently. What I have listed is really a good start for the budding kit builder.
Just a few things to think about before you go outfit your new shack workbench. While there's plenty of things you can get really cheap, a few things you should focus your budget on are a good soldering iron and a multimeter. Those two things alone will make your building experience so much more successful and rewarding.
Good luck, and to steal a line from one of my heros, see you in the soldersmoke!
