Alligator gar (a.k.a. the gator gar) has a variety of scale shapes all over their body. Scales along the back and belly are round while scales along the sides are triangular with a stem originating at the base. Shape changes gradually as you make your way around the gar’s body. Scales in other areas are oddly shaped and just plain cool looking.
The triangular scales begged to be used by Native Americans as arrow heads. The shape was perfect and the serrated edge made for an ideal cutting edge. The “stem” at the base needs limited grinding to allow insertion in an arrow shaft. Native American tribes in the Deep South with access to Alligator gar supplemented their arrowhead with gar scales. They must have worked well because scales perfect for arrowheads are found in archeological sites away from Alligator gar’s historic distribution.
If shape was the only factor to consider for making arrowheads they might have floundered as a hunting tip because toughness matters too. Fortunately Alligator gar scales are made of enamel, not keratin. Largemouth bass or carp scales are flexible made largely of a substance equivalent to our fingernails.
Gar enamel is more similar to our teeth and are the hardest bone made by living creatures. I learned how hard they are trying to gut an alligator gar with a hatchet. Sparks flew as metal shavings were freed by the fishes’ armor.
Alligator gar scales are hard, tough, sharp, and serrated. They were practically destined for archery hunting. Not so for other gar. Long nose, short nose, and spotted gar do not have serrations or any surface texture, and the “stems” are not nearly so dramatic. They are hard enamel but comparatively thin and translucent and smaller.
Making the arrow head:
Gator gar scales are almost perfect as arrow heads. The stem of the scale, or tang in the world of archery, is perfectly shaped when seen in front view; but is curved in profile. This requires some grinding of the stem so it seats properly in your arrow shaft. If you do this work on a grinder, do it so smell is not an issue for you or others – be thoughtful. Grinding bone smells a lot like burning hair. The basement is not a good place for this. Don’t ask me how I know this.
Once the tang is ground to be parallel with the arrow shaft it is ready for adhesive and wrapping. Be careful with the tip as it is brittle just like a chert of flint tip would be. If you want to keep it sharp you will want to be gentle with it.
