tip # 1
Rather than plunk them in the dishwasher, always wash your good and sometimes very expensive chef knives by hand in mild detergent and water and then rinse well. Wash the carefully, one at a time so the knife blades don’t nick eash other or your fingers for that matter. Dry the knives thoroughly before putting them away in a knife block or protective knife roll with their knife guards in place. Also don’t let them soak in the hand wash water, as that can warp wooden handles.
The harsh and often citus acid chemicals of the dishwasher soap and the extreme high temperatures of a washer itself can damage the blades and the wood or composite handles. The expansion and contraction of the handles in the extreme heat in dishwashers can loosen the rivets causing the blade to shift over time. In the dishwasher, the knife blades can also be accidentally nicked when coming in contact with other silverware or dishes and lose their edge.
Many knives such as the Chroma knives designed by Porsche of pure Japanese steel even comes with a red warning label “NO dishwasher”…!
Even though it can be a pain at times, taking the extra effort to care for your good knives will reward you with knives that remain sharper, safer and newer looking longer.(I have had some knives for 15+ years).
It will also same bit of cash and time over the years, with fewer trips to the professional knife sharpener.
tip # 2Before I begin cutting or chopping on my cutting board, I have a piece of skid proof plastic shelf or drawer liner that I place between the counter and the cutting board that will keep it anchored as I work. I like the particular one that is pictured as the tiny rectangles act as miniature suction cups and make my cutting surface immovable during food prep. When I work in a kitchen other than my own, I find that a damp kitchen towel between my cutting board and counter works well in a pinch.
I still work in the kitchen with safety as my priority...no need to spend Christmas Eve in the E.R.
