I go to Army navy surplus and buy my wader belts there..
My knife is a hijcacked 4" kitchen knife, in a leather sheath always on my right side... small and sharp It trims line and guts a bluefish fast and easy
Pliers (brand unknown) but 6+ seasons of abuse

and they still work... attached with a section of telephone cord...
The belt I have has a few small straps that snap on, sometimes I carry a 1/2" line coiled like Indiana jones, but mostly I jkust tie it around my waist then leave the long tage end with the snap ready to be unclipped
Sometimes a small surfcaster bag, with bombers and small needles, but thats only if I am far from my truck...
Canyon surf bag... all the usual crap in that, plugs, extra light (in ziploc) etc.. keeping that clsoed is a nylon dog collar with a snap buckle... doubles as a handle to lug bass around
There may be more I have to think...
