Descriptive Terms.
The various forms of implements will now be considered. As stated above, the names given the various articles are those by which they are usually known; but it may be well to define some of the terms used.
In the grooved axes, edge refers to the cutting portion; blade, to the part below the groove; poll or head, to that above the groove; face, to the wider or flat portion of the surface; side, to the narrower part; front, to that side farther from the hand, and back, to the side nearer the hand when in use.
In celts, the terms are the same, so far as they are applicable; blade referring to the lower half of the implement; that is, to the portion on which the cutting edge is formed.
