Carefully Selected Materials

The diamond knives are produced from carefully selected jewel quality octahedral diamonds. Each crystal is cleaved along its natural lattice into several thin plates which are microscopically screened.
diamond knife workmanship

Precision Workmanship

Each plate is welded onto a steel shank and following that is a high precision series of processes to lap and polish the diamond into what is unquestionably the sharpest cutting instrument made. The radius of the diamond knife edge is about 50 Ångstroms (5nm) or 30 carbon atoms and the entire length of its edge must be defect free to the same dimensions. Ultimately an exhaustive final sectioning test is performed through the entire length of the edge. Only if it is flawless is it approved for shipment and packed and sealed in its wood case.
