I did it once. Didn't have the right tools and kept having to reshape the handle base to fit the existing v. Ended up with a handle 1/2 shorter lasted about 3 months.
Get a bat maker to fit a new handle and shape it to match the one you like. Handles are the last thing ill mess with on a bat now. You need experience and only bat makers have this. Watching a youtube video or reading a post wont substitute for this. Trust me, don't try it. Pay for it to be done properly or you may wreck your current bat.
