As the name implies, this is the ideal brush to tie crab, shrimp and anything else that crawls at the bottom of salt or freshwater. You can also use this brush to form the head on any baitfish pattern, especially on the big ones like pike, musky and offshore flies. The brush is made with EP® FIBERS on a stainless steel wire with the addition of micro rubber legs and a hint of EP® SPARKLE that will bring a lifelike appearance to any of your creations.
