First time using the SWANSON Tool Co S0101 7-inch Speed Square and I’m impressed. It feels solid in hand, not cheap at all, and the markings are clear and easy to read. I like how versatile it is for quick measurements, straight lines, and angles. Made my cuts more accurate right away. Lightweight but durable enough for regular use. Definitely a handy tool to keep in my setup and I’ll be using it a lot more going forward. ... show more

    • The ultimate pocket-sized layout tool
Style: 7" Speed Square Size: 7 inch
I've owned several speed squares over the years (cheap knockoffs, bigger 12" versions, even some plastic ones), but the Swanson Tool Co. S0101 7 Inch Speed Square (Blue) is still the gold standard — it's the one I reach for almost every single time I need accurate, quick measurements on the jobsite or in my garage. After years of daily use, it's become one of those tools that feels indispensable. Build quality — built like a tank. Made of heavy-gauge aerospace aluminum alloy with a durable blue matte finish. It's tough — won't bend, warp, or rust even after getting banged around in a toolbox, dropped on concrete, or left outside in light weather. The black-filled gradations are sharp and easy to read against the blue background, no fading or wearing off. The edges are crisp for clean scribing, and the lip (heel) is perfectly square for reliable 90° marks. Features & versatility — does way more than a basic square. 7-inch size — compact enough to fit in a pocket or tool pouch, but large enough for most framing, roofing, and layout tasks. Built-in features of a framing square, tri-square, miter square, and protractor. Graduations for common, hip, valley, and jack rafters — perfect for roof pitches and angle cuts. Scribe notches for easy pencil marking. Degree scale for quick angle measurements. Comes with the famous pocket-sized Swanson Blue Book — a mini guide packed with rafter tables, conversion charts, and how-to info for roof framing. Super handy reference right on the tool. What I use it for Marking 90° cuts on lumber Checking square on frames, cabinets, decks Laying out stair stringers and roof rafters Finding angles for trim, brackets, or miter cuts Quick squaring of sheet goods or drywall As a saw guide for circular saws (the lip hooks over the board edge perfectly) Even basic measuring and scribing in tight spaces It's incredibly accurate out of the box — no need to calibrate or second-guess it. The combo of size, durability, and all-in-one functionality makes it perfect for carpenters, woodworkers, DIY homeowners, roofers, remodelers — anyone who builds or fixes things. Value is unbeatable. Usually around $10–15 (often on sale), and it lasts forever. With over 16,000+ reviews averaging around 4.8 stars, it's consistently one of the highest-rated and best-selling carpentry squares on Amazon for good reason. No gimmicks, no plastic parts that break — just a reliable, professional-grade tool at a homeowner price. If you're starting a tool collection, upgrading from a basic combo square, or just want the classic speed square that pros swear by, this Swanson S0101 is the one. It's earned a permanent spot in every tool belt I've owned. Zero complaints — highly recommend! 5 stars all day. ... show more
