Len, I had some of those many moons ago, when I was a kid!
May not have been the same company, but looks like the same product
and the bear paw name is what they used then.
Like I said, I was a kid, and never tried to use them crappie fishing, but
did for catfish rigs. Seems like I remember that they would slide down the
main line under heavy pressure, but that was probably 25 years ago.
