You waddle through the puddle to where your HAIRPIN is. You weren't issued a card when you were given this job. So, you had to use the one you had from your previous job. You were intended to be a barber, and so the HAIRPIN was quite versatile for a barber. It also comes in handy when you want it to be. One time, you used it to un-sanctimoniously off the head of a crime league. You see, the prospit card system measures how many times you shoot it, and the event where you needed to use your HAIRPIN was under very strict scrutiny. So, the hidden weapon allowed you to use it effectively.
