Awl --

You know the loop at the end of wire rope, with a crimped-type band, often
around an "eye", maintaining the loop?

For the life of me, I cain't grok how that crimp holds, at such high load
ratings. It amazes me. It looks inherently weak, but apparently does the
job.
AND, if I have seen correctly, it seems that some of these crimps are
aluminum!

I would have thought some exotic-type brazing or welding would be required
for reliable strength.

Is this crimp method readily performed in a shop with a simple arbor press?

I may be requiring some of this to be done, but it just gives me the
willies, from a liability pov.
