I know I do! In fact, my family is NOT allowed to touch my knives, and I even keep a second block in the kitchen that they can use. That might sound drastic, but I have found them in the sink dirty, beside the sink dirty, in the dishwaher and even out in the garage being used to cut hose line!
IF IT'S NOT IN YOUR HAND IT'S IN THE BLOCK!
Simple as that, if you aren't using it, clean it and put it away.
Wash and put away your knife/knives immediately after using. Allowing food particles to sit on the knife will cause oxidation and dullness.
Never NEVER run knives through a dishwasher. Only wash by hand. The force of water knocks utensils around and will cause dulling of the blade.
Keeping your knifes in ai block or some other way of keeping the blade from touching other objects is best. It you keep all your knives in a drawer they will dull quickly. The other items in the drawer will knock against the blades every time you open or close the drawer.
A good knife is a great investment if you do a lot of cooking. If you take good care of your knife, whatever price you paid for it will be worth it over the years.
