The Stiletto 7 in Carpenter Square, model STSQ7, is a compact layout square built for carpenters, framers, roofers, and serious DIY users who want faster, more repeatable marks on lumber. This is a carpenter square designed for layout, marking, and checking cuts on framing lumber and sheet goods. The big draw here is speed: Stiletto added more useful notches and reference points so you can move through common layout tasks with less measuring and less second-guessing.

Where this square earns its keep is in everyday jobsite work. The added layout notches help with marking common rafter pitches, laying out 2 by 6 material, and ripping boards. Scribe notches every 1/8 inch make it easier to drag a clean, consistent line with a pencil or scribe instead of trying to hold the tool and freehand the mark at the same time. Highly visible laser etched markings also matter more than people think. When you're working in changing light, sawdust, or moving fast, clear graduations save time and reduce mistakes.

The BOMBER cutout is one of the more practical features on this square. It is built for repeatable stud measurements and longer layout lines when ripping boards. Stiletto specifically calls out common measurements for 1-1/2 inch, 3 inch, 4-1/2 inch, and LVL layout work, which makes this tool more useful than a basic speed square that only gives you standard edge references. If you do a lot of repeat framing or need to mark common offsets over and over, that feature is not just a gimmick. It speeds up the work.

Build quality is another strong point. The square is fully machined aluminum rather than a rough cast layout tool, and that matters for accuracy and feel. Machining helps keep edges clean and consistent, which is what you want in a tool used for straight references, marking, and angle work. The hard coat anodized anti-glare finish is there for a reason too. It cuts down reflections in bright light and helps protect the surface so the laser etched markings stay readable longer.

Stiletto also adds bottom heel markings for extra marking versatility. That gives you more ways to register the tool depending on how you're holding the stock or approaching the cut line. On a bench, sawhorse, or tailgate, little details like that can make the tool easier to use one-handed and more flexible when space is tight. The one-piece heel assembly with replaceable vial shown in product imagery points to a design focused on practical field use, not just clean catalog specs.

If your work involves framing, rafter layout, remodeling, trim backing, or general lumber layout, this square makes sense. It is especially well suited for users who want a compact framing square alternative that can ride in a pouch but still handle real layout work. If you only need a basic square to draw the occasional 90 degree line, this may be more tool than you need. But if layout speed, visibility, and repeatability matter on the job, this is the kind of square that pays for itself in fewer mistakes and faster marks.
