Now these have been really popular! Handle shank is a genuine Abu Garcia part originally from an old style Abu. The knob is rosewood with a black anodized post, knob is lacquered for long lasting. Nice thing about these knobs is you can disassemble them to clean them! I hate having a piece of sand or dirt in my handle knob when I'm fishing.....always makes me feel like I don't take good care of my stuff! Each part in these handle knobs is available as a separate part, so if you were to ever wear one out (I've yet to do so) you can replace just that part. The screws in the knobs are stainless steel and the posts are anodized aluminum. Included in this kit is a chrome handle lock and screw, as well as a chrome handle nut, either left or right hand, you specify, for your reel. Handle will fit any standard Ambassadeur casting reel 6600 size and smaller. I guarantee you won't be disappointed with this purchase!
