Crow's Foot Poling Tip

[Tsuga8]

you can cut a strip of sand paper the appropriate width and "shoe shine" the insides of the slots, just pull the strip back and forth while putting some downward pressure on it to clean up the insides and put a slight curve on them

KISS. Why didn't I think of that.....

Your local hardware probably sells rolls of emory cloth for cleaning copper pipe (around 150-180 grit) which would work perfectly for your application.

I would hesitate to cut up a slightly used belt from a belt sander. I’ve done that many times.
