Initial Cleaning
Before first use, wash the knives thoroughly with warm soapy water. Rinse completely and dry immediately with a soft cloth to prevent water spots and maintain the blade's finish.
Operating Instructions
These steak knives are designed for cutting cooked meats, particularly steaks. The serrated edge allows for efficient slicing through various textures.
- Hold the knife firmly by the handle, ensuring a secure grip.
- Place the food on a stable cutting surface, such as a plate or cutting board.
- Apply gentle pressure and use a sawing motion to cut through the meat.
- Avoid twisting or prying with the blade, as this can damage the knife or cause injury.

Maintenance and Care
Cleaning
To ensure the longevity and performance of your Winco steak knives, follow these cleaning guidelines:
- Hand Wash Only: These knives are not dishwasher safe. Dishwashers can dull the blade, damage the handle, and cause corrosion.
- Wash immediately after use with warm water and mild dish soap.
- Use a non-abrasive sponge or cloth to clean the blade and handle.
- Rinse thoroughly under running water.
- Dry immediately and completely with a soft, clean towel to prevent water spots and rust.

Storage
Store knives safely to protect the blade and prevent accidental injury. Consider using a knife block, magnetic strip, or in-drawer knife organizer.
Sharpening
While these knives feature a serrated edge designed for long-lasting sharpness, professional sharpening may be considered if the performance significantly diminishes over time. Standard knife sharpeners are generally not suitable for serrated blades.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Knife appears dull or struggles to cut. | Normal wear and tear; improper cutting surface; serrations may be worn. | Ensure you are using a suitable cutting surface. For significant dullness, professional sharpening for serrated blades may be required. |
| Rust spots on the blade. | Knives left wet; not dried immediately after washing; dishwasher use. | Immediately dry knives after washing. Avoid dishwasher use. Minor rust spots can sometimes be removed with a non-abrasive cleaner designed for stainless steel. |
| Handle feels loose or damaged. | Impact damage; exposure to extreme temperatures (e.g., dishwasher). | Discontinue use if the handle is significantly damaged. Contact Winco customer support for advice. |
