Kinex marking and measuring instruments are carefully handmade in small batches to ensure accuracy, reliability, and conformity to German DIN standards.
The invisibly rivetted joints of Kinex engineers' squares are reinforced with a special industrial bonding agent, this unusual step ensures stability through a wider temperature range than you would get with rivetting alone.
The surface grinding is superb, with all edges nicely eased.
