I have a question regarding the shape of the two blades.I have the 4064 and love it. Im thinking of getting the spear point but by looking at them online they look almost the same.I know there is a difference just how much ? Also If you have the spear point how do you like it ? I realy like the Ka-Bar Dozier line. Alot of bang for your buck. Thanks for you time and answers.SGT
