I just attached a new magnetic strip and stuck 2 scissors on it - both in their sheaths. When I take off the larger scissors, it comes off with the sheath. The smaller one however, the sheath sticks to the magnetic strip. It remains there when I move away the scissors.

The magnetic strip is brand new and shiny but I cleaned it anyway; cleaned the sheath as well; no difference. I tried in a different section of the strip but it still happens. Does not happen with any of the knives. 

The sheath is made of the same leather as several other sheaths. It is dyed with pro-dye and then Neatsfoot oil.  Same technique as with several others. Thread is the same used on several others as well.

The scissors are an old Wiss brand.

Does anyone have an idea why this is happening?

Yes it is, isn't it? 

Now that I think of it, it was one of the first I made, so from a bag of Tandy scraps, if I remember right. Wonder if it is something about the scrap I used. The rest of the treatment was the same as for other knife sheaths.

One thing I noticed - if I take the sheath off the strip and re-attach it with the scissors, it does not remain stuck immediately; only after a long while. Several hours or overnight. So the effect comes on slowly.

Weirder and weirder.

The only explanation I think I can come with;  (Its my theory because it belongs to me) is that there was some sort of ferrous salts used in the tanning. All that leather has a small amount of it through the leather but its only this small sheath because it is so light weight that the magnetism is strong enough to hold it. The bigger sheath would stick as well but its weight overcomes the magnetic grip

edit to add; I just had an idea. Have you got a university or senior college near you? Take it to their science section get them to investigate it. It might interest them to do so and students can learn testing & analysis by doing so

Maybe that piece of leather came off a cow that was abducted by aliens and experimented on?:whistle:

Could just be the tip of a piece of barbed wire that broke off and healed over ..........

It was also probed, and it was the only cow with a smile on its face...it also ' jumped over the moon ' . So thats where that came from  ;)

@dikman and I have a piece of that cow! My fortune is made. :lol:

@fredk @Gezzer, some form of soft iron maybe, or metals like Aluminium or nickel or lead.

@fredk, that is a good idea. There should be a college somewhere close by with a Physics department where I can show them this. It is such an  oddity!

umm. no, just low grade ferrous metal is magnetic. Stainless steel has very little attraction to magnetism. Other metals are not magnetic

I thought the same thing but  it appear some metals do become temporarily magnetic in presence of strong magnets and these wall magnets are strong. Might be wrong, of course or the effect might not be enough to hold up even a small sheath like this one. 

Half the time when I read articles online, I am not sure if they can be relied upon; even the ones that seem to be from what should be reliable sources.
