What function is actually served by the o-ring? Many newer skewers don't use them. The cost of new skewers on Amazon isn't that much more than ordering a small pack of the O-rings...

Thanks

The O-rings fill the groove that has been machined into the QR nut to accept an O-ring. Simple!

In other words - they serve no purpose. The skewer works just as well in the absence of the O-ring. I don't know, maybe they are there to make it easier to grip the nut while spinning the QR lever before locking it. A solution to a problem nobody had, sure - but damn they look good!

They ad some grip when turning the quick release. Models without o ring have Some sort of patern (don’t know the english word) or Some form of tabs to hold onto like the later ringle twisters had

Exactly^ they were designed to give a grip on the shiny chrome surface. A lot if new skewers are not round or have ridges to grip.

Btw...its called knurling when its an cut patern.
