Folks, please don’t put your knives in the dishwasher. You wouldn’t put your firearm in there, so don’t put your knife in there. This isn’t $1 kitchen utensils we are talking about here.
Why? My lady's Spyderco Q is 440C and with all the cutouts in the blade, the dishwasher works wonders and for 15 years has done no harm. Knives aren't guns.
