What are these "eyelets"? As I said, in the (hopefully not fake) ones I looked at, the fuse wire appeared to be simply connected (by welding/brazing/soldering/whatever) to a little 'pimple' protruding from the middle of the inside of the end of the cap - I saw nothing I would describe as an 'eyelet' (unless it's this 'pimple').In some counterfeit/copy fuses no eyelet is used in the internal construction and the wire often can be seen to be
trapped against the side wall of the tube under the cap causing a bulge. ... Where an eyelet is used to attach the fuse element to the end cap it is much deeper than eyelets used by approved...
I've also been pondering how on earth they manufacture these things - in particular how they manage to attach the 'second' end of the fuse wire (unless it's soldered - which the list you posted says it's not) - any ideas?
In any event, I'm not sure what in that list of features of fakes you've just posted explains "In a genuine fuse the fuse wire is connected to the end caps in a way that reduces the amount of heat that can reach the end caps from the fuse wire" - is that in some way related to thee alleged 'eyelets?
