You never know where you might find a tool. Went into a thrift store today put on by the local humane society, and found about half a dozen DVD's. Plus a Bonney-made Matco combo wrench! The color of chrome stood right out in the bin! 10mm, and I never pass up a metric wrench these days.
Plus, I've been applying for bike repair tech jobs, so having an assortment of metric wrenches in different styles and lengths could come in handy
