While there is no such thing as luck I will paraphrase my particular belief "fortune favors the prepared" and I always carry my Leatherman Skeletool:

In a sense you can "make your own luck" by being prepared.
I hate going places where I'm not allowed to carry it.
I have the original, bulkier version. Stays in the boat, almost 20 years old now. Great tool.
I have lucky hats. They’re lucky because I like them.
Milwaukee fastback razor is always clipped in my right pocket. I rarely leave the house without it.
As far as talismans go, I do pick up a penny from the ground, as long as it’s heads-up, and chant the “find a penny” rhyme in my head. Always. The penny goes in my back, left pocket. The luck it brings may be small enough to go unnoticed, I tell myself, but
what if I hadn’t picked it up? What disaster have I avoided? There is no rational reason for any of this, yet I persist.
I also keep small items left over from my dad who passed in 2011. They don’t necessarily bring me any luck, but they feel like they do. His last Canadian fishing license, a bottle of nasty aftershave in the center console of my car, some flies he tied are stuck in random places about the house, one in the visor of my car and my girlfriend’s.
My guitar cases are filled with random things collected from gigs. Pens, a little scuba diver figure, cigarette butts, coins. They stay in there for reasons I can’t explain but they must stay or else.
