The Snow Peak Solid Stake 20 is one burly stake. The shaft is made of stainless steel, but the tip is forged. That means you can pound the Snow Peak Solid Stake into the ground without bouncing off rocks. Actually, the rocks will be crushed. In fact, you could pound these into concrete if you wanted. Theyre really that tough. A flat head minimizes slipping while hammering, while a hole in the head makes extraction a snap.
