Keep the Park Tool UK-1C Utility Knife handy in the garage, tool box, or on your belt. The ergonomic aluminum handle provides a secure grip, and the quick-change blade system uses standard utility knife blades so you'll always have a sharp edge.
If you haven't added one of these to your tool kit yet, do so. We all have plenty of nice pocket knives that will do the trick, but who really wants to break off the tip, dull the blade, or get covered with gunk & goo? Spare your beloved knife from the dirty work and add this one to your kit. Blue looks good to boot.
