Well not having one, I can only speculate. The TGLB has two guards. PLUS a lanyard hole. With that setup you could lash it to a pole thereby making a nice pike. PLUS it is a larger blade and therefore gives additional reach AND it is a thick and wide blade, both of which only adds to the usefulness as a weapon. Both contribute to a larger wound channel.
I hope my PICTURE ONLY observation helps ya Jeff, and good luck. Stay at healthy as Y'all can.
