This may sound strange to some, but I personally have lucky stuff whenever a big event comes around like a big date, a job interview, a wedding, etc. I have a lucky pair of boxers, a lucky shirt, shoes, watch, and other lucky stuff. But since I've been DE shaving I have lucky shave gear as well.
For this big events I use my first DE, my Merkur 12C; Tabac shave soap; my first brush, a Parker synthetic; and SCS Dagger aftershave. I realize these items aren't magical but they do give me a level of confidence that some of my other stuff doesn't.
Any of you guys have a "lucky" product lineup you use for big events?
