Native (North American Indian) Arrow Head

I have a few native artifacts that I, myself, have found and quite a few more that my father had collected over many years..  This arrow-head was one of his and for some reason he had shellacked one side (shown) of it for some display purpose of his own. At any rate, I like to keep a few laying around in easy view when I am reading, having tea, whatever and this one was doing its thing on the porch table and 'sure-as-beans' accidentally got knocked onto the cement porch floor, breaking about 1/4 inch of the tip off.  Using a little carpenter-like glue, I reattached the tip and had it laying on the piece of white paper while the glue was 'setting-up' - so of course it became fodder for my camera and this blog.
