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.

:shocked:
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.

So THAT is why my hard drive crashed!

We're trying to figure out why this snapped in half. The customer told us it was because he used a magnetic holder. I have no idea. I was wondering if anyone had any information about this, but I guess its a urban myth. Maybe he just didn't want to tell us he did something to it. lol

A magnetized knife will draw the iron out of meat cuttings and thus doom you and your family to a life of anemia.

Just kidding

LMAO

Good link gic

What about running a magnetized blade through something like this?

I realize it's small for a gyuto, but it would work for a parer.

I could never get those things to work that well. (on screwdrivers) but I heard they have powered ones that work better. AC electromagnet boxes.

perhaps it was a crappy magnetic holder, and the knife fell off and broke when it hit the floor.

Yea, I think that exactly what happened.
