An ultrawide tent/tarp stake I designed for snow and sand applications. Would work for gravel too.
Could also be buried by tying off to the center smaller hole if standard stake insertion methods aren't effective.
Plastic should be fine for most applications; for the most demanding needs, try getting in metal instead
Stake is 20cm long, 3.7cm wide, and 1.25 cm thick.
