ironraven I agree that you can still lose a blade even wiyh a thrusting spear. No problem there. And yes a hog will climb a spear unless you have a very strong cross bar.

I don't really advocate spear hunting as the primary mode of food gathering. But when checking your traps or fishing sets you can use it on targets of opertunity.

A spear is simply another option to have in your bag of tricks.

To Leigh Yes I like bows better myself. But it takes much more skill, pacience and time to construct even a green stick bow. Let alone someting well shaped and seasoned one.
I can build a spear in a few minutes with a simple wodden point or with a metal point if I have one in a couple of minutes. A fire hardened point in a couple of hours resting by a fire at the end of the day. Making even a green bow takes a while to get even reasonable balance and something close to an even draw.Also it takes 2 hand to use a bow. If one is out of the action you are up the creek.

While it works better with 2 a spear can be wielded as a thruster with a single hand. If you practice you can even become reasonably proffecient throwing with your off hand.
