...and what are those tacks on the handle made from? They look red.

Also, I know sgians of this period are always made with a hidden tang (as are most modern sgians and dirks, as well), but do they tend to use a two piece handle construction (glued together sandwich style), or do they tend to have a one piece construction with the space for the tang drilled out?

Because I see a seam there that's either two pieces of wood glued together, or from moulding (in plastic); sorry, but when they labled that thing as early 19th century, they lost all credibility in my eyes.
