Thanks darkwingduck.. When I saw the cap picture which post by "noobxxx" I nearly fainted. Thanks again..
the thing between shaft and handle, we normally call it "cone". it looks like a cone! the thing at the end of handle, we normally call it "cap". or end cap or butt cap. there you can see the manufacturer's logo. when you start to ask what is a cap looks like? the answer is provided by noobtron.
kinda .. but the meaning almost the same .. you dont tell detail/deeper about your questiong .. perhaps you should add 'racket' in your word ...
