MAGNETIC Commander blade!

I recently obtained an excellent condition Commander in bead blast part serrated. Much to my surprise I discovered that the blade is magnetic! That' s right, magnetic. Spine, flats, bevel and edge! It picked up some torx drive bits I had lying around. The original owner does not have a clue. Can anyone shed some light?

Steel can be magnetized fairly easily. The easiest way is to rub it with magnets or store it near a magnetic source which can magentize the metals. I have a few fixed blades (not Emerson) that have magnets in the sheaths which has caused the blades to be highly magnetized. I have a CQC7 which can drag around paperclips but not pick them up.

I wonder if the use of a magnetic chuck during grinding would cause this?

I can see it with a carbon steel blade but I thought that the stainless was nonferromagnetic. AM I wrong?
 
'Stainless' only means it has at least 8% chromium. The major constituent is still iron, so it can be magnetized.
 
Well, as mentioned the original owner does not know. So its safe to say that he did not store it next to a big magnet! However, Paul, your idea is something to think about. I' ve used wheels before but what exactly is a "magnetic" chuck? Is this what is used in the Emerson factory? Please feel free to elaborate. Thanks.

I don't know if chuck is the right word, but I don't really know what to call it. I've just read that CRK uses a magnetic holder for grinding. That is one of the reasons that Chris Reeve doesn't want to make Talonite Sebenzas. It would require completely changing their manufacturing techniques. I have no idea what Emerson Knives uses and none of my Sebenza blades are magnetic. I was just trying to throw out possibilities.
 
A magnetic chuck, is a flatground piece of steel with copper wires imbedded, these act as a magnet when electrified, holding the workpiece on to the chuck for grinding or milling.
They are mos often used for flatgrinding, and when you need to remove the workpiece you demagnetize the chuck, and this is why the blades are not magnetic anymore.

I work as an engineer at a bearing manufacturing plant and we use magnetic chucks for all of out race grinding. These chucks are VERY strong magnetically. After you get the work off the chuck, you must pass the work through a demag or the magnetism will remain. Just like after you put a magnent up to steel, only much worse.

Also, about the stainless. There are two kinds of stainless. One of these is not ferrous. I think maybe 304 stainless is like this and not magnetic - do any of you have 304 stainless guards or anything?

Hope this eliminates some confusion.

Most helpful info! I am learning something new about chucks and grinding. I' d wish someone from Emerson could verify if this could be the case. Any further comments and thoughts out there? I' d like to hear more. Thanks.
