We had a course of making a knife in school so here is the first of that kind from my hands. I'm in no hurry in making a second one. I had no use for a kitchen knife and I don't have the knowledge of making them as efficient as possible so I skipped that one. In stead, I do know what kind of knife is good for stabbing and cutting and all sorts of killing, thanks to training on knife fighting in my youth.
With the handle I focused on a good grasp in different positions. I also tried to have the peak of the blade in a good angle for successful penetration into human flesh.
