Common Lisp. The only tool I use with it, I guess would be emacs. Unless by "tool", you mean libraries. However, it's Ruby (often generated by Common Lisp) that puts food on the table these days -- and Python that I'm using to plot my (positive) escape from the workforce. Both Ruby and Python are weaker languages that share some of the Lisp spirit. Ruby in fact, is derived from Emacs Lisp. One of my side projects is an attempt to jack libraries from Python -- which will, if successful, make Common Lisp more usable as a day-to-day programming language.
