While I have fished for Walleye and Sauger for over 25 years I have never had one cut my line with their teeth. They would have to swallow a plug or jig very deep to get to the line. They do however have plates on their gills that will cut you or line. Fishing the Cumberland River, I use a medium action rod with 40lb. braid line because of hangs and stripers. I cast heavy jigs with curl tails and swim flukes or stick baits like Husky Jerks or Rattlin Rouges. If fishing from the bank, look for eddie brakes and deep holes. Don't be afraid to ask the locals for tips.
