Start with observable form, not a name. Photograph the whole object, then compare its base, stem, notches, flaking, symmetry, cross-section, material, and measurements with catalog references.
Photograph the features used for comparison
Outline and symmetry: take a straight-on full view.
Base and stem: take a close, head-on view of the hafting area; note straight, concave, convex, or bifurcated form.
Notches and flaking: use even light to show side, corner, or basal notches and visible flake scars or retouch.
Profile: take an edge view to show thickness and cross-section.
Material and scale: record observable material and include a ruler or measurements when possible.
Photo comparison cannot establish authenticity, provenance, cultural affiliation, age, value, or legal status. Review candidates and alternatives carefully.
