I found this nifty Re:Solve Paint & Prep Tool on a clearance deal @ Lowe's for $1.24!

Designed by Wagic, this tool features 11 tools for paint and prep work. Inside you'll find a locking square blade putty knife, scraper, caulk squeegee, paint can opener, caulk tube opener, 2 Hex keys, and 4 screwdrivers.

For light duty, like painting & prep, this tool should hold up well. I wouldn't attempt any tough mechanical tasks though. The paint can opener also doubles as a bottle opener, a nice bonus. I like the flexible caulk squeegee, but I know I'll lose it eventually.

Keep an eye out next time your in the paint department @ Lowes.
