One of the hobbies that I have come to enjoy when I am at the beach is shark tooth hunting. Cherry Grove Beach offers such a great place to hunt for shark teeth. You do not have to have any equipment at all, but I use a sink strainer on the end of an old composite shaft golf club and a Tic-Tac container when I go out hunting. You can get the old clubs at a Thrift store for a dollar or two and the sink strainer at Walmart for 99 cents. Cut the club head off and use a galvanized wire to make a frame for the strainer. I use electrical tape to dress up the frame and zip ties to fasten the strainer.
The key to finding shark teeth is all in the timing of the tide washing through the shell beds where the shark teeth are bury. Some of these shell beds can be buried under the sand a foot or two deep. Cherry Grove Beach beach was built up from sand out from the beach in October 2019 so the shells and shark teeth are always in the process of washing back down. Yes it is fun and rewarding, but you must be patience and keep looking. Like any other activity the more you practice (just looking for the shark teeth) the more you will find. If you want you can find them just laying on the beach, but you will find a lot more in the breaking surf on the shoreline. However, every day will be different since the waves, wind and the currents are never the same. So enjoy, I know I do.
