Half-Axe Information.

Basically the half axe was larger than a tomahawk but smaller than a felling axe.

Then sometime around 1750 a new pattern began to
evolve from the boarding axes of the time that were heavier and
much more compact with a straighter, shorter, thicker spike and
a "half axe" style blade.

Names can confuse as well as clarify, and this is especially true

of the tomahawk. For years students and writers, archeolo-

gists and collectors have been accustomed to using names for

specific forms or general categories of hatchet or tomahawk. They

refer to squaw axes, half axes, or to French, Spanish, Minne-

wauken, Woodlands, or English types with the calm assumption

that these are accepted terms and will be understood.

A final general term occasionally encountered is the half axe or

half hatchet. This derived from the era when axe blades frequently

flared out symmetrically. In the half axe only the side toward the

hand flared out. The other side was straight or curved slightly in

the same direction. In the era considered here, the half axe was

the normal form for hatchets and felling axes, and the term itself

was becoming obsolete. 6

In early examples, spiked tomahawks were sometimes made with shanks for insertion into a wooden shaft in much the same manner as the usual halberd type. In such instances they were normally forged from one piece of iron or steel. One specimen found near Rome, New York, seems to have

been made by applying a small conical spike to a standard half axe.

Johnson, Reynaldo Address unknown. In 1808 he delivered 178 half axes at 500 each and 22 tomahawks at 400 each to the Office of IndianTrade. https://archive.org/stream/americanindianto01pete/americanindianto01pete_djvu.txt
