If you want to get the spear just to have, then get it. However, I would recommend instead the Cold Steel Bushman, which, when needed, can be used as a spearhead. When you don't have it attached to a stick, it can be used as a versatile and dependable fixed blade. The quality of the Bushman's blade is most definitely well above the spear you linked.

There are two versions:
