I haven't even had my first razor yet but I wanna be prepared before I get it this christmas. I've been doing a lot of research and I need to know something. What exactly is a scuttle? and how does it compare to bowls and mugs?

As a side question: How can I get a cheap mug, bowl, or scuttle? most of the ones for shaving are fairly expensive (for the budget of a 15 year old).
