Quality Control

From the selection of the finest raw materials to exacting and rigorous steps taken to maintain quality control during each phase of production, there is over a century of craftsmanship that has gone into every IVO knife, transforming a simple cooking task into a uniquely pleasurable experience each and every time.
Rockwell testing equipment (HRC) is used to maintain strict control over the all important hardening process. Resistance to corrosion and cutting edge superiority are entirely dependent on this precise heat treatment process.
To ensure optimum performance, our patented sharpness testing machine is used on every knife blade that we manufacture, guaranteeing the best possible performance with every knife.
Throughout the production process, proper grinding and honing angles are continuously monitored with a laser angles control unit.

The quality of steel Quality knives require a very specific grade of steel to insure proper forging, tempering and hardening. All IVO knives are made of the finest quality, high carbon no stain stainless steel. Our commitment to quality insures durability, strength and longevity of each blade that is made. All IVO knives are quranteed to resist rust and corrosion for the life of the product.
The forging process The way which the knife is forged and tempered is as important to the process as the quality of the steel that is used, Forging is the process of heating steel to a red-hot state prior to applying a powerful blow to form a forged blank.
