Yes, however, the quality of those instructions can vary somewhat. NO one is expected to imagine what the PE designer was thinking when he made the fret.
A special tool is nice, but dowels, sharp #11 or a good set of nippers, some needle nose pliers will get you through.
It's a good idea to lay yhr fret on lo-tac tape to cut out the small part to keep them from flying of to the other dimension where lost parts go.
