Simple and classic, I love this heavyweight canvas with a thick leather handle as a work tote.  I appreciate the reinforced bottom for its ability to stand-up on its own - all the easier as I throw everything but the kitchen sink into it!
 
I also use these strong totes to organize individual project/client files and store heavy tile and material samples.  You can use the long strap to carry it as a crossbody bag, or detach the strap for a small hand-carry tote.
