The Titanium series of the Martinez Rapid Framing Square is derived from the original Martinez square from customer feedback. This square features a non glare matte tumbled surface finish on the titanium blade and deeper laser etched marking. Each Titanium blade is CNC machined around the perimeter and heel mounting locations to ensure high accuracy not typically found on this type of square. The ballistic grade titanium material will provide many years of use and is very durable and corrosion resistant. The CNC machined aluminum heel assembly of the square is a matte finished hard anodizing with stainless steel hardware. This square is available in either “imperial/inch” or “metric/millimeter” dimensional units.
