Being nwe in this forum, I hope my English might be good enough to make you understanding my issue.
What Iīm interested in, looking for the answer since years and getting many different answers, is, how long the blade of a knife should really minimum be to reach the heart of an adult bear. That depends of the size of the animal, of course. In case of a black bear for example, letīs say around 300 pounds, I suppose a length of 6 to 7 inch should work. But whatīs about a 1000 pound up grizzly?
Please letīs not talk about the chances anyhow and about such stuff, that a spear, hand gun cal. 500 or a cannon is by far the better choice letīs talk about the knives. Itīs only for the psyche,because Iīm aware about the chances. But nevertheless thatīs extremely important.
Making survival trips in Europe, Canada and Alaska, Iīve been among dangerous animals lots of time. Last June tracking near Kodiak Island I used my bear spray and hurt myself never will take this kind of defense again. As I donīt carry shooting weapons, I have to trust in a good knife. Is anyone in this forum with anatomical knowledge? Have my doubts while looking at an 8 inch blade and thinking about the size of a very big bear . I know that the heart is not the best idea to kill a bear, but thatīs what I like to know. Also it is said that the heart is pretty close to the chest wall similar to a human being. By having that in mind 8 inch might work. On the other hand the knife shouldnīt be unnecessarily long, as it has to be fast to handle that means as short as possible.
Also the tip shouldnīt be shaped as knives like Busses, as those seems to be not pointed enough, and the CS trailmaster for ex. might have a too thick blade, means to slow in action.
For any helpful informations in this issue thanks in advance. Youīre the last hope.
