Standard tent stake that come with tents are often cheap and need to be replaced so I thought I would share this website that sells a new kind of tent stake:
www.x3anchorstake.comThere are videos on the site demonstrating it being used and even pounded into a 2x4. It won't bend or rust and the head doesn't mushroom when you pound it into the ground (using whatever you have available!). You can also twist it with an upward motion and back it out using your hand or a tool.
Take a look at their website. They offer a guarantee.
