Our MK2 T-Square blades are cut from 1.5mm stainless steel and precision laser cut and then machined to give a perfect fine edge. The handle is machined from 6082 aircraft-grade aluminium with our signature hexagon pattern design and then anodised black. The blades and handles are then moved to our laser department, where they will have the precision markings laser-annealed. The T squares are also checked on our vision measuring system to confirm the accuracy of the machining and markings.
