...what do you guys use ?
[this one is a 1 5/8" base x 2 1/4 " depth side fin. It is for use with a decent sized [ back ] single fin ..... it still needs extra foiling , thinning the back edge more ]
...Chipfish, if you dont have electrical tools, you can do it with a file...put the fin on a wrench and use the file...its easy
Hi Chip, Use a small angle grinder with a 'flap disc' you can get them from most hardware stores. Very handy tool. But be sure to cover all traces of flesh first, those itches are a drag. Cheers.
