A cook knife is the central tool in food preparation, designed to slice, chop and dice ingredients with a single, long blade. The blade runs from heel to tip in one continuous curve, allowing a rocking motion that keeps the edge in contact with the cutting board. This motion transfers force efficiently from the handle to the blade, reducing effort and increasing precision. The broad surface also lets the chef guide the knife with the free hand, controlling thickness and uniformity of each cut without shifting the grip or repositioning the food.
To use the knife, the operator grips the handle firmly, places the tip on the board and rocks the blade through the ingredient in a smooth arc. The heel starts the cut, the mid-section follows through, and the tip finishes it. For larger items, the knife is lifted and brought down in a single stroke, using the full length of the blade. The purple colour marks the knife for a specific station or ingredient, preventing cross-contamination in a busy kitchen.
The blade is made of stainless steel, resisting corrosion and maintaining sharpness through repeated use. The handle is shaped to fit the hand, reducing fatigue during long service. The 385 mm blade length allows the knife to tackle large vegetables, joints of meat and whole fish without needing to saw or tear, preserving texture and presentation.
The HACCP note confirms the knife meets hygiene standards for food-contact equipment, ensuring it can be cleaned and sanitised to professional requirements. The 842 mm overall length provides balance and leverage, while the blade width gives stability during the cut.
Cleaning follows from the materials: the stainless steel blade is washed, dried and stored separately to prevent damage to the edge. The handle is wiped with a sanitising cloth to remove food residue and bacteria. The purple colour remains vivid through repeated washing, maintaining its role as a visual identifier in the kitchen.
