Find Your Angle With Tajima Slant Tools
Calculating rise over run isn't like horseshoes and hand grenades--close won't hack it. With Tajima's slant tool, you don't even have to calculate. Instead, you just directly measure the angle with a quick check and a turn of your thumb.Toolmonger

Preview: Milwaukee V28 4-1/2” Grinder
The latest tool in Milwaukee's ever-expanding V28 line, this new 4-1/2" grinder is a 28-volt monster that won't leave you tripping over cords. We're excited to see how it performs, as most cordless angle grinders have, in our experience, proven a bit wimpy for daily use.Toolmonger

Lock Pick Tools
In some parts of the country, carrying a set of lock-picking tools in public will get you a trip to the local lockup. That fact alone makes these tools a cool and dangerous product. Many insist that lock-picking is a great hobby and that the tools are uber-handy to have around—we can see why.Toolmonger

Knipex Insulated Ratchets
Though it looks like a Fisher Price offering, the Knipex insulated ratchet is far from a kid's toy. Knipex designed this ratchet for high voltage—way past the Christmas lights realm. These suckers are rated for 1,000 volts.Toolmonger

The Bostitch 23-gauge headless pinner kit shoots headless pins, dramatically reducing fill work. Best of all, headless pins virtually eliminate jamming--so you won't find yourself stuck when you need this gun the most.Toolmonger
