Why does washing knives in the dishwasher dull them?
In: 890
Been washing my knives in the dishwasher for years. The knives themselves are even more years old, never been sharpened.
Sure, I bet they’re not the sharpest knives in existence, but we’re talking ridiculous amounts of subjective “sharpness” here. I just used one to cut fruit, veg and chicken (in that order). Nobody would say it didn’t do so like a “sharp” knife.
This is one of those “if you have thousand-dollar knives and think you can tell the difference” things, and for most people it’s just not relevant for a kitchen knife because most of the things you cut with it aren’t even hard.
The only knife I’ve dulled in the last 10 years is the one that I literally use for absolutely everything from boxes to being an impromptu screwdriver to cutting through plasterboard, to cutting up thick plastic. It took years to dull it.
Furthermore, knives with rivets in the handle shouldn’t be washed in the dishwasher. The handle material and the steel have different densities and under the heat of the drying will swell at different rates. This will eventually loosen the rivets.
