found this int he TN regs....
I don't agree with it........
Agree with the 1 yr mark but the 2 year mark can go to an inch but should alos say the end is rounded and not sharp or to a point.
3 years is okay but again should say the tip to a point.
4 yrs - sharp and slightly hooked.
What have you guys seen....agree or disagree...
