Railroad spikes are used to protect your home or business from unwanted negative energies. If you own your property, hammer 1 into each of the 4 corners of your land. If you are renting, keep one at or near your front door. You can also place a railroad spike cross in your home or place of business. This is basically marking your terrritory. 
These railroad spikes have been gathered, ritually cleansed, blessed and dressed with the appropriate protection oils and herbs by Mama Toni.
