I wanted to share something I’ve done for years that helps a lot when fishing current, esp. when you get crazy tides.
Just pound your egg sinkers flat using a hammer, on the concrete. A steel substrate works better (like an anvil) but I usually just use the sidewalk.
I have a small metal rod that I have no idea where I got it, but I spray it with WD40, or lithium grease (whatever grease is handy). Insert it into the sinker, let it just barely poke out the other side (so you aren’t having to pull a lot of rod out). Hammer the sinker flat, use pliers to pull out the rod. You also don’t need to “pancake” the sinker. Just flatten it out some. The whole point is to keep it from rolling.
Expect to mess up a sinker here and there, sometimes they do split, but you’ll get the hang of it.
The flat sinkers stay low in the sand and they don’t roll. I usually use 1 ounce or 2 ounce sinkers.
Also note, I’m sure you can buy these already made this way, but I make my own sinkers, and I don’t have a mold that makes flat slip sinkers, but I do have a hammer that does
