Glossary - Parts of a Projectile Point point parts graphic

Base - the bottom end of a projectile point.
There are several common projectile point base shapes:

    Straight base -the edge of the base is flat
    Concave base - the base is indented
    Convex base - the base protrudes proximally

Blade - that part of a projectile point above the hafting area. A flintknapper commonly makes the blade more distinctive by side notching or corner notching the projectile point.

Hafting area - the portion of a projectile point secured to a spear, dart, or arrow shaft.

Notch - an indentation on the sides of the blade or at the corners of the base. Flintknappers notch projectile points to create a different way to attach the point to the spear, dart, or arrow shaft.

    point notch graphica. Corner-notched point - a point with indentations placed where the side of the blade and the base of the point meet.
    b. Side-notched point - a point with indentations on the side of the blade
    c. Unnotched point - a point with an unnotched
    hafting area, also often called lanceolate-shaped points.

Stem - a type of hafting area of a projectile point created by side notching or corner notching the point.

    point stems graphica. Expanding stem - a stem that diverges towards the base.
    b. Contracting stem - a stem that converges towards the base.
    c. Straight stem - a stem with parallel sides.
