Problems of existing knives When you chop food with a knife, food sticks to the side of blade due to surface tension on the side of blade as well as action-reaction forces with which the materials try to return to the original state.
Solution of ISAAC knife Since ISAAC knife has 1 cm wide sloping embossed blade, it fundamentally removes the surface tension so that food materials do not stick to the side of blade. (physics theory of Isaac Newton) Since ISAAC knife blade is handiwork, it can solve this problem.
Sub-zero Treatment with ice-hardening Special heat treatment with quenching from 1060°c to -80°c provides high hardness and durability, contributing to outstanding sharpness and no-stain finish.
