I "discovered" PEC tools of California and was so impressed I bought some of their stuff to put it to the test of daily use.  I am still impressed and I now recommend PEC's premium line of combination squares.

I use my PEC combination squares when I am traveling, when I need an adjustable blade, or when I am measuring a 45 degree angle.  Its a "jack of all" squares for hand tool woodworking.  I recommend and use the PEC 12 and 6 inch models.  Here is why:

• 6 inch long blade.

• 4R Graduation scale: 1/8ths & 1/16ths, 1/32nds & 1/64ths

• We stock the premium "hardened steel" body - not the cast steel body - it makes a big difference in accuracy over time.

• Blades are fully hardened and tempered, and come with a durable, satin chrome finish.

• The high contrast, micro fine graduations are well marked, and very easy to read.

• Its a "Jack of all squares." Allows you to measure and mark 90 or 45 degrees, adjusts to configure for just about any situation, and remains very accurate.

• If you can only have one square this combination square is what I recommend.

• Square/miter head features level vial and hardened scribe.

• Knurled adjustment knob is very easy to grip.
