This is a Daiwa genuine tool specifically designed to remove the special handle knob caps found on Daiwa products, such as Egi-ing caps. I used it once. I am listing it because I will not need it in the future. (Compatible Knobs) CV-Z103, RYOGA BJ-W Kouga series, Emeraldas series Egi-ing Wood Knob Power Light S Knob, Power Light M Knob, Power Light L Knob. Thank you.
