Years ago,I chisel pointed some,like Fred Bear used to.The problem with a chisel or round point,is that you can no longer check tip alignment on an alignment jig or by spinning on the tip.This is important to me,not only when installing the head but I think it is also important to check tip alignment after any shot in the field.
For that reason,I would no longer chisel or round off a point.These days,I would tanto the point,if I weren't using heads that already had one.This tip is strong but also has a point so it can be spun.
To do a tanto,I first check tip alignment on a jig.Then I scribe a center line,off the existing point.Now,when I file in the tanto,the centerline keeps my new point in line.
