Thread: Magetic knife

    Magetic knife



    Today I was told that magnetic knife holders/strips will weaken the strength of your steel and when it finally breaks after a few years... You can do this.

    I'm trying to find out more about this, but has this ever happened to you?

    I don't actually use mag strips, I keep my knives in my knife bags, safely set aside out of harms way.

    Oh dear! Thats scarry! Is it the magnatism that weakens the steel or the side-loading stress that occurs with putting the knife on and off the strip?

    Meh... Going to need a lot more evidence to back this one up. A single anecdotal instance is just not enough. That blade could have broken from SO many other possible scenarios other than being weakened by the mag strip.

    Seems to be a bit of an urban myth according to the straight dope

    In a post sometime ago Son said that carbon blades have a tendency to go magnetic. I also noticed the knife I had bought from him was slightly magnetic.

    I don't think this is possible. All surface grinders have magnetic chucks. If magnets weakened steel there would be a lot of broken tooling in the world.

    LMAO! Sure it can. Wrap an inductive coil around your knife and crank the current up! But a magnetic holder? BS. Utter BS. Yes, all carbon steels subjected to magnets can themselves become magnetic. Heck you can even magnetize steel with a sharp whack of a hammer. Reflects nothing on the quality of the steel.
