5 pointers for keeping your knives sharp

Dull knives can slow you down because they require more force to cut stuff. They're also dangerous because they're more likely to slip when slicing, putting your fingers at risk. Factory sharpening doesn't last long, so it's up to you to keep the edge sharp. Here's how from the experts at Consumer Reports.

Do hone. That smooth-looking edge on a chef's knife, paring knife, and slicer actually has superfine teeth like a comb. When you chop straight down, they get messed up. Honing on a steel sharpening rod straightens them out again, restoring the edge.

Don't scrape. Avoid scraping the edge of the knife across your cutting board to scoop up chopped food; that dulls the knife. Use a pastry scraper for the job instead.

Do use the right cutting board. Wooden cutting boards are the most forgiving; polyethylene is a close second. Cutting on a plate or other hard surface such as tile or glass will ruin the edge.

Don't put knives in the dishwasher. Even if the manufacturer says it's okay, always hand-wash knives. Excessive heat and chemicals take their toll. Wash with soap and water, and dry immediately.

Do store them right. Use a block or a wall-mounted magnetic strip. Avoid drawers, where edges can knock against each other or other kitchen implements.
