Great review. I'm always curious about why people want to use a knife as a spear though. I'd just sharpen a stick and fire harden the tip. Pretty much as effective as a blade on the end and much better balanced. A big plus is you still have your knife for chores or emergencies without having to dismantle the spear every time.

If I'm missing an important aspect of using a knife as a spear, please let me know. I'm not picking on you, this has always made me curious and this just seemed like an opportunity to ask.
