The Snow Peak Solid Stake #30 is one burly stake. The shaft is made of forged steel, with black electrodeposition coating. 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. They're really that tough. A flat head minimizes slipping while hammering, while a hole in the head makes extraction a snap.
