1" Antler Point

[1bugman]

Was talking to my young nephew (new Hunter) about antler points, and I Know what it says in the book,

Antler Point-Deer: A projection off any part of
the antler measuring at least one (1) inch in
length measured from the longest side. Eye
guards are antler points if they are at least one

They used to have a diagram showing how to make the measurement. Just wondering if an LEO's have pictures of what is and what isn't a 1" point and how to make the measurement. Thanks
