The square has a tempered, blued, spring steel blade.
The blade is secured to the body with decorative brass diamond washers and steel rivets.
These squares have been tested on both the inside and outside faces, with the internal angle being twice as accurate as the British Standard, an accuracy better than 0.01mm/10mm blade length.
