OK, So I'm at work right now and my .22 GW was in my desk without it's sheath. I go and pull it out of the drawer to use it and there were 3 staples stuck to the satin blade. I then took out a small allen wrench, set it on the table in front of me, hoverd the GW about 1/4 inch above it and the allen wrench lifts up and partially sticks to to blade like a weak magnent.. I know some steels have slight magnetic properties but I had no idea infi was one of them. Any of you folks experience the same thing. I am assuming coated blade won't have this affect because of the thick crinkle. I have never had any other blade do this to me.. Anyone have insight on this?

-thanks
 
I would say the field should fade with time. If you have one of those old tape erasers, you may be able to demag it pretty quick if it's a problem. No telling what phase of the manufacturing process imparted a mag field on it. Could be from a mag particle inspection somewhere down the line.

Just my .02
 
All steel is magnetic, but not all steel is magnetized, as your knife seems to be. The magic of iron!
 
My GW and AD are that way too, I noticed when I placed a beer cap on it and when i went to use the knife it was stuck, and the AD has a stronger field.
 
I think Garth hammered on it right after its heat treatment to align the domains. Such the jokester. ;)
 
magnafluxing will do this, your knife may have accidentally been magnafluxed with the special batch that was done a while a go :thumbup:
all the mole jacks received fluxing i believe...


Magnafluxing, developed originally by Carl E. Betz, is a method of testing ferrous metals for surface and subsurface flaws. The component being tested must be made of a ferromagnetic material such as iron, nickel or cobalt, or some of their alloys. This test is often used on industrial tools, and engine parts during maintenance inspections. It can also be used to diagnose failure, as in crash investigations.

It works by applying a magnetic field to the component under test, using e.g. a permanent magnet. This will cause a high concentration of magnetic flux at surface cracks, which can be made visible by dusting iron powder or a similar magnetic material over the component.

Parts can be tested using one of two methods. The wet method consist of bathing the parts in a solution containing iron oxide particles. The wetted part is then placed in a magnetic field and inspected using a black light (ultraviolet light). The iron oxide particles are attracted to surface discontinuities or cracks, where the magnetic field is discontinuous. The particles flux around the imperfections and the patterns are visible under the black light.

The dry method is based on the same principle. Parts are dusted with iron oxide particles and charged using a yoke. The particles are attracted to the discontinuities and are visible by black light.
 
It was common enough from 1999 to 2002 for new Busse knives to be magnetic.

Just search for the old threads about it.
 
Skunk, when are the blades inspected? Is it a final process or something that's done when they're still blanks? And do you know if it's done with DC or AC current?

Hmmm... I've checked a number of my Busse blades in the past, and none of them were magnetized.

magnafluxing was a term also used in quantum leap:

"This side-effect of uneven amnesia is called Swiss-cheesing or (as a technical term in the show's universe) magnafluxing, which prevents him from remembering most of the details of his own life."
(wikipedia : the uquestionable source of all factual information in the universe)
 
You have discovered the secret of how having one attracts another, then another, then another....:cool:;):thumbup:
 
Recent custom SFNO was slightly magnetic.

I just figured it was trying to lure a CG SFNO my way.
 
I noticed most of the blue GW's were magnetic, but only half of the pupmkins.
I wonder if they were cut out of the samer sheet?
 
I tested my blue .22 GW and it is also magnetic.

My xxxl nick is not magnetic at all. .

Interesting stuff!! Thanks for all the insightful posts folks.. Much appreciated :thumbup:

sorry for the poor quality pics,

I have this magnetic experienced this with some custom made knives. The reason for it in my case, was simply because the maker used a flat grinder with a magnetic table- keeping the knife blank in place.
