Consider donating your tools to a qualified charitable organization. Sure, everyone can use some cash, but a donation will warm your heart and qualify for a tax deduction.
Donate your tools to a VO-TECH. Public Schools
qualify as non-profit groups approve by the IRS (not for-profit schools like ITTtech). Or, how about Habitat for Humanity? Or another qualified organization that is close to your heart (the IRS has a search tool http://www.irs.gov/app/pub-78/
You have to itemize and there are different reporting requirements depending the Fair Market Value of what you are donating (items in "good used condition or better" - thresholds at $250, $250-$500, $500-$5000, and more than $5000) check out http://www.irs.gov/publications/p526/index.html
to see the rules.
In bad economies charitable organizations see marked drops in donations - so they could really use it.
