When pulling them?

I’ve only used them a few times. Are they pretty much 100 percent reusable?

Yes, reusable.and I've bent my share of them. Just hammer them back into some semblance of shape.

Same here

I have bent a lot of them! Duckbills are my favourite and I reuse them! I don’t even know if they still make duckbills, since I bought a whole bunch years ago.

Yep, but I rarely pull 'em anymore. Cut the cable and go.

If you want to pull them...go to PCS Outdoors and buy those 7ga Fangs they make. Only $40/100. You WON'T bend those pulling them.

Super stakes for me. Bang in a piolet hole and use anything to push down the stake end, pull back and you are done. I have heard that some people have broken them but I have not......jk

If you have a good auger and drill, you can just drill down beside the chain/cable, and they'll usually just pop out without too much trouble.
