Black & Decker Modular Matrix System
Most modular tool systems we've seen simply let you use the same battery packs for lots of different tools, virtually ensuring that you'll have one ready to go when a chore calls. The Black & Decker Modular Matrix System ($30-$70) instead lets you choose from one of three base units that connect to a variety of attachments, including a drill, impact driver, oscillating multi-tool, jigsaw, sander, router, and trim saw. Thanks to lithium-ion batteries that hold a charge up to 18 months, you can rest assured you're powered up and ready with the right tool for the job. [via]
