Ferrules

Rods for travelers were made with nickel-silver metal joints, or ferrules, that could be inserted into one another forming the rod.

Since the 1980s, with the advent of flexible, yet stiff graphite ferrules, travel rod technology has greatly advanced, and multi-piece travel rods that can be transported in a suitcase or backpack constitute a large share of the market.

The instrument has tenons on both ends of the instrument, suggesting the presence of now lost ferrules or turnings.
