Of course, many of us have a deep-seated belief that you can never have enough tools.
I frequenly will have two or more of the same type of tool. I was recently asked if I had a staple gun and when I replied that I had two (a manual and electric), my non technical friend just cracked up laughing. I didn't see the humour.
A lot of my projects use development boards that have 25 mil square wire-wrap pins on a 0.1" grid. I like to insert these into a perf board and then use good-old 20th Century wire-wrap to connect them up. It's quick, easy to fix errors, and easy to dismantle to re-use the boards in other projects.
Solderless breadboards are also great for quick projects, but don't expect them to stay intact if you have cats :-)
If you solder parts on a circuit board, sooner or later you will have remove one because you installed the wrong part, need to change the value to get the circuit to work, or you make a mistake and let the magic smoke out. To minimize the chance of damaging the board you need something to help remove the solder.
I prefer the larger spring loaded solder suckers. I never found a small one that works well. Solder braid is another option, but you have to buy more as you finish a roll. It also does not work as well at getting the solder out of plated through holes.

My wife just got a new cat (her last one passed away age 17 a couple of months ago). This new one is a very energetic kitten. I heard a disturbing sound yesterday evening -- when I looked up it was strolling across our breakfast table, upon which was my current Arduinoi project with a rats nest (no pun intended) of wires. I don;t think I need to describe the end result (sad face)

I've used both the braid and the solder sucker -- each works best in different cases. Recently I read about someone who used a "blower" rather than a sucker -- but I don't remember much about it -- do you know anything about this technique?
