knife arm on 14t

[born2ride]

The ball that rotates on the arm is getting flat spots on it. they spin free by hand. what could be causing the wear. unless it was previous damage that is just show up now from use. they are nice and clean but very worn.

Has anyone change the blade on this item . If so with what type of blade. part Number would be great.
