This is a product I actually purchased and really used. I went boar hunting and this particular model was on a list of recommendations. I wound up getting this one and the marketing was full of shit like this.

It did get the job done. My chief complaint is that I think the blade should be bigger because if I'm getting that close, I want to make a bigger hole. That and the crossguard should be bigger.

But outside the very niche hobby of hunting things with spears I can't think of a single practical use for this thing that there isn't a readily available, far better alternative. Maybe home defense if you have a felony conviction so you can't own a gun and that's the best yku can do.
