Why we made The Knob Blocker - Radio knob guard
At Skookum Works, our mission is to create products that solve real-world problems and enhance safety and efficiency. The inspiration for The Knob Blocker, the portable two-way radio knob guard accessory, came directly from the field. Our founder, a member of the Squamish Search and Rescue team, experienced a serious safety concern while hanging under the long line of a helicopter. He accidentally bumped the volume down to the lowest setting on his radio, which resulted in not being able to hear anything without realizing it.
