For disassembling the center pole on an Advanced Elements™ AirFusion™ Kayak. The pole can be difficult to disassemble (e.g. when it ends up full of sand and water from a failed surfing attempt). This tool makes disassembly easier by holding down the pin and providing a larger non-cylindrical gripping surface. Align with the pole edge and use the circular cutout to rotate into alignment before attaching the tool. I used a M5 x 6mm screw to hold down the pin (it protrudes 1-2mm beyond the cylindrical wall).
