You can request anything. I've never heard of re-knurling a bar, but it could be done for enough money. How much money do you have?

Couldn't you just remove the sleeves and put it into an albeit large lathe? Do a couple of tests first to find a nice knurl though.
you realize knurling requires a lathe right? It would be a big pain in the ass, first you have to find a lathe thats long enough for the whole damn bar, shave off the diameter of the whole shaft to make it even and bare all the away around(you just can't re-knurl on the old knurl)and re-knurl the bar. A lot of work
Yeah, a new bar is cheaper. But you can always just ask the owner to get it re-knurled. He's got lots of money.
Actually, the lathe would only need to be long enough to fit about half of the bar along the slideways or even less if you don't want the middle portion re-knurled as the bar shaft can go through the lathe spindle. Then you just have to find the right sized knurling tool and line it up right.
Having said that, I've never renewed a worn out knurl but I have finished off a knurl that's only been half applied... And as far as I'm concerned, judging by the eleiko bar and every other bar in my gym, a fully formed knurl is very rare.
Just ring up a local machine shop and ask them how much it would cost to get a bit of solid round bar re-knurled.
