Conservation Corner: Pipe Tomahawk
This artifact is a single-handed hatchet from North America.
General-purpose tools, they were often employed as a hand-to-hand or a thrown weapon. There is a pipe-bowl opposite to the cutting blade and a hole drilled down the center of the shaft (for smoking tobacco). A decorative soapstone bead, group of feathers, and an orange pom-pom are held together with green yarn and attached to the stem with leather lace. Furthermore there is a band embellishment of brass tacks (metal studs) around the diameter of the haft.
In general the iron axe-head was rusted, the brass areas, decorative string, and pom-pom were soiled, and the feather embellishments were damaged.

Importantly, the rachis of one feather had split apart, and the feather was held together only by the integrity of the barbs. Therefore the main conservation technique involved a modified form of the veterinary treatment imping: implanting a splint inside the rachis of the feather to repair it.

This treatment, along with careful, specialized cleaning revitalized the tomahawk and revealed some unique characteristics. For instance, an unusual pattern of circles was uncovered on the axe head which was previously obscured by rust and a possible maker’s mark was uncovered on the pipe bowl which could provide more diagnostic information in the future.
