Friction calls will never seem the same after you get a hold on
one of these! Knight & Hale has taken four of the most popular
friction call surfaces in the land and combined them with their
patent pending Integrated Soundboard and WIP Technology (Wood
Impregnated Plastic).
K&H's WIP Technology in the pot and striker handle combines
plastic with wood particles to add the fuller sound of wood while
retaining the durability of plastic. The Integrated Soundboard
features raised spirals built right into the pot, creating
incredible resonance and volume.
The Yella Hammer features a Sla-Tek surface and comes with a
Power Tip Striker.
