2. Safety Guidelines
Always prioritize safety when handling any knife. Improper use can lead to serious injury.
- Keep Sharp: A sharp knife is safer than a dull one, as it requires less force and is less likely to slip.
- Proper Grip: Always maintain a firm, controlled grip on the handle. The textured nylon handle is designed to minimize slippage.
- Cutting Surface: Use a stable, non-slip cutting board. Avoid cutting on hard surfaces like stone or metal, which can dull or damage the blade.
- Away from Body: Always cut away from your body and fingers.
- Storage: Store the knife safely in a knife block, magnetic strip, or with a blade guard to prevent accidental cuts.
- Children: Keep out of reach of children.

4. Operating Instructions
The Mercer BPX Breaking Butcher Knife is specifically designed for breaking down large cuts of meat. Its unique curved blade and robust construction make it suitable for tasks requiring both precision and strength.
Using the Breaking Knife:
- Breaking Down Meat: Use the curved blade to follow the natural contours of bones and joints when separating large primal cuts. The curve provides leverage and allows for long, smooth cuts.
- Trimming Fat and Connective Tissue: The sharp edge and sturdy blade are effective for removing excess fat and tough connective tissues from meat.
- Slicing Large Roasts: While primarily a breaking knife, its length and sharpness can also be utilized for slicing large cooked roasts.

5. Maintenance and Care
Proper maintenance ensures the longevity and performance of your Mercer BPX Breaking Butcher Knife.
Cleaning:
- Hand Wash Only: To preserve the blade's edge and finish, always wash the knife by hand immediately after each use.
- Method: Use warm water and a mild, non-abrasive soap. Gently clean the blade and handle.
- Drying: Rinse thoroughly and dry the knife completely with a soft towel. Do not air dry, as this can lead to water spots or corrosion.
- Dishwasher Safe: This knife is NOT dishwasher safe. High heat and harsh detergents in dishwashers can damage the blade and handle materials.
Sharpening and Honing:
Regular honing and occasional sharpening are crucial for maintaining the knife's performance.
- Honing: Use a honing steel regularly (e.g., before each use) to realign the blade's edge and maintain its sharpness.
- Sharpening: When honing no longer restores the edge, the knife will need sharpening. This can be done using a whetstone, pull-through sharpener, or by a professional sharpening service.
6. Troubleshooting
Most common issues with knives can be resolved with proper care and maintenance.
- Dull Blade: If the knife feels dull, it likely needs honing or sharpening. Refer to the 'Sharpening and Honing' section.
- Rust Spots: Rust spots can occur if the knife is not dried completely after washing or if left in a damp environment. Minor spots can often be removed with a non-abrasive cleaner and a soft cloth. Prevent by always drying thoroughly.
- Loose Handle: If the handle feels loose, discontinue use immediately and contact Mercer Culinary customer support. Do not attempt to repair it yourself.
