Slightly magnetized New 10V?

[MMC]

Hello,

New member but yearslong fan. Just got a 10V Shaman in and noticed while comparing it with my Manix 2 SPY27 that the steels were a little attracted to each other when the finger choil nubs touched. Upon further goofing off with my various steels, it seems that the 10V is attractive to my SPY27 and M4, and Pd1, slightly attracted to Maxamet, and not noticeably sticky with s45vn. (I took a video but could not get it attached to my post)

Is there any way that the production of the knife made the 10V magnetic? Or perhaps some metallurgy answer that I couldn't find on google?

Thanks
Max

I have experienced the same with my new Dodo in 4V.

Welcome to the forum. I read on Google that exposure to a magnetic field can make steel temporarily magnetic, since iron is a ferromagnetic material. Could that be what happened?

You can buy this magnetizing blocks for a few bucks at any hardware store.

Pretty much every time I reprofile a bevel, the steel dust forms a magnetic field pattern on the blade, and the heavier I have to reprofile the more it happens. Maybe it's static?

Working/stressing the steel causes the magnetic poles to align, is my guess.

There's a lot of factors that can cause materials to magnetize for apparently random reasons. They're not really random, but we're just not paying attention to all the little things that are constantly going on around us.

The need for that demagnetizing block is a perfect example. How many times are you working on some tiny contraption, you pick up a screwdriver, and the little screw just sticks to it? How many times are been working in the dirt, and you find tiny flecks of iron stuck to your tool? They're a bear to get off!

It's really kind of cool that just sitting here in front of our computers or phones, we get to see first hand an experiment in electromagnetism.

Interesting thread. I was never aware that magnetizing could happen on a Spyderco blade.

I do own a Victorinox SAK Mini-Champ and a Rambler, each of which have the small Phillips screwdriver / cap lifter tool that is purposely magnetized, so small screws have a lesser chance of getting lost while workingwith them.

Not a spyderco, but a friend at work asked me to sharpen his cold steel ti lite in aus8 and it was magnetized enough to pick up the liners. It has just sat on his dresser for months, and I held onto it for a couple of weeks not next to anything magnetic, and I took it apart to clean it before I ever started sharpening it. So it seemed permanently magnetized.

I get that too actually, but on really any of my blades. I always assumed it had something to do with the magnets underneath the sharpening stones I was using. Maybe that's enough for the steel dust?

Well that's definitely part of it for me now, I have magnets under my Edge Pro but I made a post asking about this probably 14 years ago way before I got magnets.

The surface grinders used in the manufacturing process of many production knives hold the blades in place by strong electromagnetic force. It's not unusual for blades to retain some degree of magnetism.

Stay safe,

Pretty normal from the grinding, and easy to accidentally magnetize part of it from quick contact with a rare earth magnet on something.

You can get relatively inexpensive powered table top demagnetizers that you can quickly run metal objects over to remove it if it bothers you, those small tool ones won’t help you at all with larger items like a pocket knife.
