To maintain a knife:
- Also use a cutting surface made for a knife, like a cutting board.
- Don't keep your knives in the same drawer as other silverware, preferably you have a block made for the knife to rest in.
- Always hand wash the knife... don't put it in the dishwasher.
To sharpen a knife: Go out and buy yourself a sharpening steel. When you notice that the knife is duller than usually, sharpen it. To do this, there are a few key factors you need to know:
- Keep the sharpener vertical.
- Hold the knife at a slight angle to the sharpener.
- Stroke downward and towards yourself.
- Alternate strokes, and do an equal number of times on both sides.
