So I accompanied my husband to the hardware store last month and thought that there might be something there that would work and not be so expensive. We stopped at Harbor Freight, which has nice prices. This is what I found:
This one is a Reamer Tool for a Circuit Board and cost $1.99. I have not used this one yet, but I have had it out of the package and it feels wonderful in your hand as well. This one is smooth and has a point on both ends. You can hardly beat the cost.
I will bet that the makers of these tools never thought of this use. Give them a try, and I think you will love them as much as I do.
