Bobby; The safest saw I would use is one of those jeweler's hand saw and small miter box. You have a lot more control over your cut, and it will be the cheapest, most accurate saw you will ever buy. However, if you are talking a power saw, I'd recommend a band saw. It will have the thinnest kerf of any powered saw. A band saw is also useful for other cutting jobs around the shop. In MHO it also allows you the best control over your work piece also.
By the way, that's a really nice pen, first try on not!
