Crafted axe - Kakofu

Japanese: 加工斧 - かこうふ

...In the above explanation, the blade and handle are described as almost parallel and perpendicular because they are often worn at a slight angle depending on the user's dominant hand and ease of use. Axes as woodworking tools can be broadly divided into two categories: felling axes, that is, axes used to fell trees and roughly split them, and processing axes, that is, axes used to split them into smaller pieces and carve them. In archaeology, when classifying axes, the shape of the axe blade is emphasized, and axes that are symmetrical when viewed from the side are called double-edged, and those that are asymmetrical are called single-edged, and are called double-edged stone axes, single-edged stone axes, etc. ...

From [Stone Axe]

...In terms of construction, there are chipped stone axes, which are finished by simply chipping, ground stone axes, and ground blade stone axes (also called partially ground stone axes), which have an axe head made of natural gravel or a head that has been chipped and shaped with a ground blade. Because stone axes are primarily used for woodworking, a distinction is sometimes made between felling axes (for cutting trees and rough cutting) and processed axes (for gouging and cutting). However, there are chipped stone axes for woodworking and digging. In cultures that did not have ground stone axes, such as the Mesolithic period in Northern Europe, the chipped stone axes were for woodworking, whereas in cultures where ground stone axes were widespread, such as the Hassuna culture of the Iraqi Neolithic period and the Jomon culture in Japan, the chipped stone axes were for digging.

Japanese:

…なお，上の説明で刃と柄とがほぼ平行，直交と記したのは，使用者の利き腕との関連や使い勝手で，やや斜めに着装することも多いからである。木工具としての斧の機能は二つに大別され，伐採斧（ばつさいふ），すなわち立木を伐採し，これを荒割りする斧と，加工斧，すなわち，小割りしてえぐり削る斧とによびわけることができる。考古学では斧を分類するとき斧の刃の形状を重視し，刃を側面から見て左右相称のものを両刃，非相称のものを片刃とよび，両刃石斧，片刃石斧などという。…

【石斧】より

…作りから見ると，打ち欠いただけで仕上げた打製石斧，磨いて仕上げた磨製石斧，自然の礫（れき）を利用した斧身か打ち欠いて整えた斧身に，磨製の刃を加えた刃部磨製石斧(局部磨製石斧ともいう)がある。石斧の主用途が木工用であることから，伐採斧(伐採･粗削り用)と加工斧(えぐり･削り用)が区別されることもある。しかし打製石斧と呼ばれるものには，木工用と土掘り用とがあり，北ヨーロッパの中石器時代のように，磨製石斧をもたない文化の打製石斧が木工用であるのに対して，イラク新石器時代のハッスナ文化や日本の縄文文化のように，磨製石斧が普及した文化の〈打製石斧〉は土掘り用である。…
