is that true

[treegje]

if you wash your knives in hot water

The structure of the metal changed (softer)

And the knife will be faster blunt
is that truth?

 

[smokebuzz]

unless your water is 600+ degrees,no

 

[bustintires]

the powder dish soap blasting at the blade might tank the edge off a little but ya haf to sharpen them any how.

I've never had a problem with my knives in the dishwasher. But I always run them on a steel right before I use them anyway.

No that isn't true...You must anneal them first some forms are heating steel till d-magnetized and soaking in vermiculite for a slow cooling process. And that is the basics on how to soften metals

What he said. It would take probably over 1200F to start to temper the blade - depending on how it was heat treated in the first place and metal chemistry.
