The Empire E255 6 in. True Blue Blade Pocket Combination Square is a compact layout and measuring tool built for carpenters, remodelers, woodworkers, and serious DIY users who want a square that is easy to carry but still accurate enough for real work. This is a combination square designed for layout, measuring, and checking 90-degree and 45-degree angles. Model Number E255. If you need something for quick markups, trim fitting, small stock setup, or checking level without dragging out a larger square, this is the kind of hand tool that earns a permanent spot in your pouch.

What makes this one useful on the job is that it does more than just mark a square line. The 6 inch stainless steel blade has inch graduations with etched markings that stay readable after repeated use, and the True Blue vial gives you a quick level check when you are fitting material or verifying alignment. Empire also calls out accuracy within 0.001 inch for the vial system, which is a real benefit when you are working on finish details or trying to keep repeated cuts consistent.

The head is precision machined for accuracy, which is what separates a decent pocket square from one that actually helps you work faster. If the head is off, every line is off. Here, the machined head and rational dimensions are built to give you dependable reference surfaces whether you are checking a corner, marking a cut line, or setting a small part for drilling or assembly. The compact size also makes it practical for cabinet work, punch-list work, and tight spaces where a larger framing or combination square just gets in the way.

Empire's Blade-Lock feature is there for one reason: faster adjustment with less slip. Set the blade where you want it, lock it down, and keep moving. The self-aligning draw bolt helps with quick measurement changes, so if you are stepping off repeated marks or transferring the same dimension across several parts, you are not wasting time fighting a loose blade. That is the kind of small feature that matters more after a week of actual use than it does on a spec sheet.

Durability is also handled the right way for a tool in this size. The blade is stainless steel for corrosion resistance and long-term legibility, and the body uses a sturdy machined head with a high-visibility blue finish that is easy to spot in a cluttered bag or on a bench. There is also an onboard scriber pin, which gives you a cleaner, finer mark than a carpenter pencil when you are laying out metal, plastic, or finished stock where line width matters.

The Empire E255 6 in. True Blue Blade Pocket Combination Square is best for users who need a compact measuring and layout tool for trim work, woodworking, light fabrication, punch-out tasks, and general shop use. It is not trying to replace a larger square for sheet goods or full framing layout. It is built for the fast, frequent checks that come up all day long, and that is exactly why a good pocket combination square gets used more than people expect.
