What does magnetism mean on a blade?

Hi Gav,
You're right, such rubbing action certainly might in some degree cause some static electric type effect.
In looking back on this topic, I was rereading Jens' thread on magnetic blades from 2005 (now in the Classic Threads file) and this discussion was incredible! While about 99% of it was so far over my head, it was still so well worded that it was even understandable to me, and fascinating.

Apparantly 'Mare Rosu' (Gene) had a dagger from Mysore that had some sort of multipolar magnetic phenomenon going on, and different parts of the blade had magnetic poles facing alternate directions! Even Dr. Ann Feuerbach, who wrote her Ph.D paper on crucible steel came in on the discussion, and was as intrigued by the topic as all the rest of us.
I found references in Pant ("Indian Arms and Armour" p.90-92) where the smelting of ingots in regions in Hyderbad contained magnetic schist mixed with haematites and black ferruginous sands and were exported to Persia, Syria and East Africa from Cutch.

It was noted in the thread that magnetization can occur from grinding and sharpenening or various 'working' of the blade, which would fall in line with your suggestion of repeated rubbing. Apparantly, polishing stones sometimes include lodestone, again toward these possibilities.

Apparantly, my thought on magnetic application to a blade to suggest quality, i.e. steel from sources such as this sought after Hyderabad product was suggested by Tom Hyle (Feb. 20, 2005) in this classic thread.

Fearn, nothing at all wrong with the 'way cool' theory

...in fact, pretty neat idea in sword combat....the other guys sword gets dragged to your blade. Wonder why the Zorro guys didnt think of this..a magnetic sword and all the soldiers swords fly toward Zorro's

Hmmm. on second thought !
Really bad visual!

All the best,
Jim
