Understanding Cutco Knives and Dishwasher Safety

Materials and Construction of Cutco Knives
Cutco knives are renowned for their high-quality materials and expert construction. The blades are crafted from high-carbon stainless steel, providing exceptional strength and maintaining a sharp edge over time.
The handles are ergonomically designed with a unique material known as thermo-resin, which ensures a comfortable and secure grip. The combination of these materials results in a knife that is both durable and easy to handle.
General Recommendations for Knife Care
To ensure your knives remain in top condition, it is important to follow general knife care recommendations. Knives should be cleaned promptly after use and before food dries on them.
Using a mild detergent and warm water is advised, followed by thorough rinsing. It is also important to store knives properly, using a knife block or sheath to protect the blades from damage.
Dishwasher Use and Knives
While many modern dishwashers have settings for cutlery, it is commonly advised that high-quality knives should not be cleaned in a dishwasher.
The high heat, prolonged exposure to water, and abrasive detergents can lead to damage over time, affecting both the blade and handle.
Cutco’s Stance on Dishwasher Safety
Cutco recommends against placing their knives in the dishwasher. Their official stance is that hand washing Cutco knives is the best practice to maintain their sharpness and integrity of the handle.
Following the manufacturer’s guidelines will ensure the longevity and performance of your Cutco knives.
The Impact of Dishwashing on Cutco Knives

How Dishwashers Work
Dishwashers clean through a combination of high water temperatures, powerful water jets, and abrasive detergents. While effective for many dishes and utensils, this process can be too harsh for delicate items like high-quality knives.
Potential Risks to Knives in Dishwashers
The force of water jets can cause knives to knock against other items, potentially dulling the blade or causing chips. The heat can also warp knife handles, especially those not designed to withstand such temperatures.
Effect of Dishwasher Detergents on Knife Blades and Handles
The chemicals in dishwasher detergents are designed to break down food residues, but they can also have a corrosive effect on knife blades, leading to dullness.
The handles, particularly those made from thermo-resin, may degrade over time when exposed to these harsh chemicals.
Longevity and Sharpness of Cutco Knives with Regular Dishwasher Use
Regular dishwasher use can significantly decrease the lifespan of your Cutco knives. The sharpness of the blade may be compromised, and the overall integrity of the knife may suffer, necessitating more frequent sharpening or replacement.
