If you have a broken fishing rod handle, the first thing you need to do is identify where the break is. If the break is near the reel, you will need to replace the entire handle. However, if the break is further up the rod, you may be able to repair it with some adhesive and/or tape.
Once you have located the break, clean both sides of the break with some rubbing alcohol. This will help ensure that your repair will hold. Next, apply your adhesive or tape to one side of the break and then align the two pieces of the broken handle together. Hold them in place for a minute or two until they are secure.
Now your fishing rod handle should be as good as new!
