I'm a tool junkie. I can't help myself. For the past 18 years I've been bringing you the finest tools from around the world. Here's another one from Germany to add to your collection. This puts the typical "thumb screw" adjustable wrench to shame. The articulating jaw is of unparalleled design. The push button action, with 18 indexed positions, slides smoothly up and down to accommodate any size fastener up to 2 3/8". Zero backlash, parallel jaw movement, and 10:1 leverage ratio for superior gripping power. Replaces a complete set of wrenches! Buy them now as I've only ordered a limited number for us tool junkies.
