The BKK Feathered Spear 21-SS feature natural feathers and reflective fibers to enhance the presentation of the lure. When added to the back of a topwater bait, crankbait or spoon, they undulate and spread when pausing, enticing more strikes imitating a minnow s tail movement. The treble is their extensively-tested Spear 21-SS featuring a SS coating and needle point for excellent penetration. Binding thread is covered in epoxy resin to improve durability even after many strikes.
