We would recommend one of our double sided DiaFolds.
If the blade is in decent shape, the ExtraFine/Fine version should be good.
If they are in pretty rough shape I would recommend the Fine/Coarse
If you have a wide range of issues, I would recommend both a ExtraExtraFine/ExtraFine + Fine/Coarse.
There are a ton of different broad head designs out there. Some require you to dissemble it first.
Here is an funny review/instructional video of our Diafold and how to use it.
