Within the present boundary of Bontoc Province there are three distinct patterns of wooden shields in use in three quite distinct culture areas. There is still another shield immediately beyond the western border of the province but which is believed to be produced also in the Bontoc area.
First, is the shield of the Bontoc culture area. It is usually about 3 feet long and 1 foot wide, is blackened with a greasy soot, though now and again one in original wood is seen. The upper part or “chief” of the shield is cut, leaving three points projecting several inches above the solid field; the lower end or “base” is cut, leaving two points. Across both ends of the shield is a strengthening lace of bejuco, passing through perforations from front to back. The front surface of the shield is most prominent over the deep-cut hand grip at the boss or “fess point,” toward which a wing approaches on both the dexter and sinister sides of the front of the shield, being carved slightly on the field. This is the usual Bontoc shield, but some few have meaningless straight-line decorations cut in the field.
In the Tinglayan culture area, immediately north of Bontoc, the usual shield is very similar to the above, except that various sections of both the face and back of the shield are of natural wood or are colored dull red. The strengthening of bejuco lacings and the raised wings are also found.
Still farther north is the Kalinga shield—a slim, gracefully formed shield, differing from the typical Bontoc weapon chiefly in its more graceful outline. It is of a uniform black color and has the bejuco lacings the same as the others.
The fourth variety, made at Bagnen, immediately across the Bontoc border, in Lepanto, and probably also made and certainly used near at hand in Bontoc, is quite similar to the Bontoc type but is smaller and cruder. It is uncolored, and on its front has crude drawings of snakes and frogs (or perhaps men) drawn with soot paint.
Banawi area, south of the Bontoc area, has a shield differing markedly from the others. It is longer, usually somewhat wider, and not cut at either end. The lower end is straight across at right angles to the sides; the upper end rises to a very obtuse angle at the middle. The front is usually much plainer than is that of the other shields mentioned.
Throughout the Bontoc area there is a spear with a bamboo blade, entirely a wooden weapon. The spear is employed in warfare, and is losing its place only as iron becomes plentiful enough and cheap enough to substitute for the bamboo blades or heads. Even in sections in which iron spears are relatively common the wooden spear is used much in warfare, since spears thrown at an enemy are frequently lost.
Sharp-pointed bamboo spikes are often stuck in the trails of war parties when they are returning from some foray in which they have been successful. These spikes are from about 6 inches in length, as among the people of the Bontoc area, to 3 or more feet, as among the Ibilao of southeastern Nueva Vizcaya. The latter people nightly place these long spikes, called “luk′-dun,” in the trails leading to their dwellings. They are placed at a considerable angle, and would impale an intruder in the groin or upper thigh, inflicting a cruel and disabling wound. The shorter spikes either cut through the bottom of the foot or stab the instep or leg near the ankle. They are much dreaded, and, though crude, are very effective weapons.
