… i consider the Swiss Tool Spirit to be just about the perfect multi-tool, but it is also on the heavy side. Most tools designed for extreme compactness (like those for the keychain or watchpocket of your jeans), however, leave something in toughness to be desired … many feel like toys. A good compromise for me is the SOG44. Similar to the earliest Leatherman tools, this is a lightweight and compact friend in your pocket. It even comes with an old-school leather sheath. The tools are inside the handles and do not lock, but you can flip those pliers open just like your favorite butterfly knife. The SOG44 is also light on your wallet.
