If you ever find yourself searching for a wrench so you can change the blade or adjust the bevel on your saw, this professional-quality wrench-free jig saw from Porter-Cable may be the perfect tool for you. It features a reliable and strong-holding quick-blade-change system that eliminates the need for a hex wrench. Although the pinch-and-twist mechanism takes some getting used to, it's easy to change blades once you have it down. The mechanism accepts only T-shank blades, but offers a reliable blade grip. The base bevel adjustment is also tool-free, and involves popping out a built-in crank from behind the saw, giving a few twists to loosen, and then giving a few more twists in the opposite direction once the bevel is set. The shoe has detents at 0, 15, 30, and 35 degrees, but you can set it anywhere in between. This jig saw has a hefty 6 amp motor with more than enough power for professional applications. It features a variable-speed trigger, as well as a variable-speed dial. The 9543 jig saw kit also offers a dust blower to keep your line clean, along with orbital cutting action that features varying degrees of orbit--from full for soft wood to none for metal cutting. It's clear that Porter-Cable put a lot of thought into the design of this saw. The result is a professional-quality saw that's easy to use but doesn't sacrifice any essential features. --Brian Trinen
