P&C Tool 8715 Half Hatchet, Tube Steel handle (aka carpenter's hatchet).
Belonged to my great-granddad, who used it for splitting kindling. I rescued it from a pile of basically scrap metal I found in the old coal bunker in the basement and cleaned it up. It tends to accompany me for most jobs when I may need a hammer or hatchet, but don't need the dedicated tools. I'm slowly learning how to sharpen axes, and I'm getting an edge now that is better suited to chopping and felling than just splitting.
P&C was founded in 1915 in Idaho and moved to Oregon in 1923. They were bought out by Plomb (Proto) in 1941, and remained with them through several buyouts. While the production of P&C-branded tools ended in 1974, they continued making items for Proto's sub-brands until 1990.

They say that Miller's Falls started producing carpentry tools for P&C in 1965, which is the first year this model shows up. Miller's Falls produced a camper's "belt axe" that was also sold as P&C, but this one definitely isn't from Miller's Falls. It bears a strong resemblance to a True Temper product from the Jet Rocket line, even down to the red-painted collar between the handle and head. Thus, I believe it to be rebranded True Temper.
