Planform The Planform stage can be thought of as the final form an artifact assumes before "finishing" characteristics (such as notches, stems, tangs, etc.) are added.Franciscan chert is a California-specific lithic, not to be found in other states, with the possible exception of inter-tribal trading amongst the ancients.It's my own personal theory that the size of the point coincided with the size of the "game" being sought; consider the difference shown in the photo below, between a Western clovis point and its eastern counter-parts.The "grip" for using this tool is shown in the last photograph.This conserved material and effected a sharp edge nicely.Items were bartered for the needed stone implements, and I can imagine that some were likely "traded for a promise".And my answer is this.This is an interesting "trigger" pressure flaking tool made from an animal bone with almost no modification to become a useful tool.A blank is a lithic which the Native Americans roughly worked-down at rock quarry sites for ease of transportation as well as for trade.
