It is most common in the older points ie. paleo and transitional points. The edges were apparently ground so as not to damage the binding. The edges on these points at the base appear to be more polished than that of the cutting edge. Under magnification, you may also observe striations from the grinding process. That is my non-technical explanation. There are others more qualified in this room to give you a better description. Hope it helps anyway. If you have access to any paleo or transitional points take a look at the base. You can often feel the difference by rubbing your finger across the edge.

PHere are some examples illustrating basal grinding
The first two are Palmer points that have had the base ground flat for hafting, presuming to avoid splitting the shaft.
Here are 2 Rowans no grinding on the left point, the right point exhibits grinding half way toward the tip, even the flaking scars have been removed.

Yes that is correct not only does the basal grinding make it less likely it would cut into the binding it also strengthens the base in that area.
On this Dalton the area outlined in red was heavily ground. If you have a jewelers loupe 10X power is good enough or a magnifying glass start looking at your points with it close ups using magnification will help you get a grip on this terminology.
Waterglass meet Butch he is a great guy. If you do a search on his name in the forum you will find many older posts attributed to Butch. He is a great guy with a lot of NC artifacts knowledge.
