What is the best quality, "coolest" knife I can get? I have a thing for weapons.
The best knives are those you forge yourself. Its also very cool making your own blades, axes and swords. It is not easy but you have greater control over the end product. Example I have a low angle filleting knife with a 10° angle with a total of 20° angle in a full flat grind. It is very difficult to maintain the edge but it is razor sharp. A 17° degree angle is found on scalpels, so it's almost twice as fine as a scalpel. It cannot chop at all. I do not use it on any meat with bone in it. I typically use it for boneless pork loins, fish for sushi and stuff along those lines.
That said here's one of the many cool weapons videos from the tube of you.
