>>452501> Knives are very hard so that they will hold an edge. They are, therefore, very brittle and not very tough. Axes are about as hard on the bit/cutting edge as good knives are on the spine and softer toward the poll. This makes them not quite as able to hold an edge as a knife but much more able to withstand impact. Axes are also made of different steel alloys than knives. Alloys that have greater toughness. you have no idea what you are talking about
