Hand Tools You'll Need

Certainly, the standard set of screw-drivers and pliers are handy, but a few hammers are also necessary.  I use a smaller steel hammer, but also a mallet because there's less damage (impact is spread over a larger surface).  And squares ... oh yes ... both fixed and movable squares are essential.  Then finally, as most people quickly learn, you cannot have enough clamps.  Right now I probably have 3 dozen different clamps, and honestly, I'd like more (but I make do).  And finally, I'd guess a coping saw should be on this list as well.
