Handwash Knives

Knives get really dull in the dishwasher, so if you want to save on sharpening, I’d recommend handwashing your knives. I didn’t believe this one at first, so I tried a little experiment and found that with the dishwasher, I have to sharpen my knives about twice as often as when I handwash them, with similar use. I assume it’s due to all of the friction from the moving water in the machine, but I could well be wrong on that part. All I know is that there is something to handwashing that is easier on knives.
