A special higher-carbon steel material is used to enhance stiffness, coupled with a forged shank to enhance hook robustness. The stainless steel baitkeeper consistently provides straight rigging and superior holding power, and is covered in epoxy resin for improved durability.

Epoxy resin finish is also applied to seal the hook eye, ideal for tying Snell knots with braided lines preventing line damage and slippage. The BKK Heavy Cover is designed to endure and perform when fishing through thick layers of grass and other heavy covers.
