When it comes to items you're going to carry everyday, the more functionality you can fit into a smaller package, the better. The TPT Titanium Pocket Tool takes this seriously. Measuring three inches long, an inch tall, and just 4mm thick, it's made from grade 5 titanium alloy, and manages to pack in a mini pry bar, flat head screwdriver, 1/4" hex bit driver, an opening for attaching a lanyard or keyring, a bottle opener, scraper, measurement cues, camping fork, finger-safe box opener edges, and 15 sizes of SAE and metric wrenches. It's compatible with standard utility blades as well, making it one of the most versatile chunks of metal you can keep in your pocket.
Driving nails all day can take its toll. Make it hurt a little less with the Fiskars Isocore Hammer. It uses a hollow design with a hidden insulation sleeve to reduce vibration by up to four times, making each strike more comfortable without sacrificing power or accuracy. Available in multiple sizes and in framing, general use, or finishing guises.
