If you're looking for a compact utility knife that fits comfortably on a keychain, you can't go wrong with the Rexford R.U.T. (Rexford Utility Tool). This RUT V3 has a milled triangle pattern and a few key changes from previous versions. The titanium multi-tool measures just 3.5" overall and features a unique mechanism to lock the razor blade within the body, and, using the standard slots on the top of the utility blade, it allows the user to slide the blade out and lock it in place.
