In emergencies, pretty matters very little. Most people carry a "beater" knife in rough situations. There are knives for collections, knives for showing off, and knives for using. But most knives here look strong enough to take abuse, so I would not worry.
Everyone hates to scratch the new Weatherby rifle stock. But after the first scratch, you get to enjoy it more.
QUESTION: Are the tubes as strong as pins would be? Why? Great idea for multiple tubes. I would rather have a knife tipped spear than a knife in hand, in most emergencies wild animal situations. Keeps you from having to hug the mad animal while poking her. LOL
