Needle tips?
 

I'm using clover bamboo size 8 circular needles and I've noticed that the tip of the right needle is wearing down. What do I do? I'm not even half way done with my project. I know it's happening because when I'm knitting the right needle rubs on the left needle in the exact same spot with each stitch. Any ideas?

You could try to sharpen it again by hand shaping with sand paper....
