This is a foreign territory for me except in one instance: having been in photographic sales (cameras, lenses etc) and also in Hi-Fi sales back in the seventies and 'eighties when performing wasn't keeping a roof over my head.
What I think we must remember is that traders have never changed, in that they get out of bed in the mornings to make as much money as possible (seems perfectly reasonable). "CAVEAT EMPTOR" is the example of our response to those tricky dealers who think nothing of adding anything to a product's description in the hope it will stimulate sales.
It prevails right across history and, naturally, still exists everywhere today. "DIGITAL" was appended to all and sundry back in the 'nineties as a way to imply state-of-the-art technology - even if it was a washing machine that they were selling!
Traders being well aware of the ultra-high standard of the ULFBERHT blades (that were probably in very short supply) would be quite content to add the moniker to anything in their stock. I don't know enough about this issue to apply this to those blades in question but consider today's system of making subtle modifications to the moniker in order not to contravene trademarks etc; or to suggest "even better!" of the product.
Just thought I might remind everyone of the realities of retail.
