Mercer: How to Clean and Store Knives

Watch this video to learn how to clean and store knives.

Place the blade of the knife on the flat surface with the edge facing away from your body. Flip the knife and wipe the other side of the blade as well. Dip the knife in the solution and then take it out. Using a cloth soaked in the hot water solution, scrub the blade of the knife. Do it very lightly to prevent scratches. After you have removed visible dirt from the blade of your knife, clean the handle with soapy water. Rinse the knife thoroughly under running water. Dry the knife by using a clean dishtowel. Wash kitchen knives immediately after using them so that the food does not dry on their blades. It is never accepted to place your knife in a drawer without a plastic guard. Make sure that knives lying on flat surfaces are never covered with towels or napkins. After handling a knife, lay it down in a clear area with the blade and point away from the body and away from the edge of the table or cutting area. A knife guard is a rigged plastic sleeve that fully encloses the blade. A glass knife block sits on the counter offering convenient access when working and when safely putting knives away. A magnetic bar is a wall mounted magnetic bar design to hold knives firmly in place.

Mercer: Knife Handling

Watch this video to learn how to properly hold a knife

Grasp the knife by the handle allowing your thumb and index finger to rest on the blade for support. Before handling a knife, put a light to medium duty cut resistant glove on the hand opposite of the hand that holds the knife. The glove will stay on the hand until the knife has been cleaned and properly stored. Use the right knife for the right job. Keep it sharp.

    One of the best fillet knives I have ever owned. It is very flexible for these curves around certain bones. I have owned this knife for close to a year and looks just like the day I purchased it.

    This knife was sharp and ready to work right when it arrived. It has a great, strong 7" blade that makes cutting up meat easy.

    Many of my previous cheap knives were rusted, even though the product description stated that they wouldn't rust. This knife accidentally sat in water for an extended period of time and didn't rust. I couldn't be happier with the quality of it. Definitely would recommend!
