I tought my self to flint knappe at age 12 becouse I was fascinated with arrowheads. Then when I got intobowhunting my dad and I were making a split rail ceder finceone dayand I deiced to make a bow.It became an obsessionto harvest a deer withwhatI had made. I was 16 years oldand it was a small doe, I never tried it again it was just somthing I had to accomplish. I made pinetrees with flutson one side all 7/8 in.wide and between 110 and 120 grain and antler tips for knocks.My bow I made was about 45 pound.
