I have been making a lot of ABO hunting points for others and myself lately. I have settled on a method that others may also use but I have also found usefull. I always thin with percussion and finish a basic triangle with the antler pressure flaker. When finished I start shortening the point from the tail till the desired wt is obtained.
Here are a couple thoughts about why this is benifical to me:
A- prevents mistaken overshots that result in having to rework the entire point
B- provides an additional method for thinning the tail of the point
C- provides a method to reduce weight without changing design
D- Helps thin the notch area
I have a couple points that I will photograph and post here in about 30 mins.
