Local Hardware Store
For a simple DIY metal key chain, you really can’t go wrong with stainless steel or aluminum options from a local hardware store. Look for round stock (around 1/4 inch diameter) in either stainless steel or aircraft grade aluminum. These materials can then be cut, shaped, sanded, engraved or painted by hand for a custom DIY key chain.
