Did knives improve

Answer 1

Several improvements had been made over the knife's history. They was originally simply pieces of broken flint,rock, etc. People realized that this primitive tool often resulted in cutting their own hands so they learned to refine the tools by the use of flintknapping. This made it to where one end could be much more dull then the other and gave them more control over the sharpness. (compared to simply finding them)

This was further improved when humans discovered they could add dissimilar material to the knife to act as a handle(as the earlier method still could result in getting cut). The earliest handles was likely to be crude materials such as sinew, strips of animal skin with gum tar, etc.

Then we go into the bronze, iron and steel ages to where the blade material itself improves (stone knives are some of the sharpest in the world-but the edges are easily chipped) This is likely to be when handle material started improving as well with things such as antler, bone, woods, etc. Some ancient Persian blades have been found with even gemstone as handles.

In modern times is when one can really see how far the knife has come. We now have particle Metallurgy steels made specifically for knives, cheaper synthetic handle materials such as micarta that is resistant to moisture and temp changes, much more refined heat treating processes, more efficient methods of making knives, etc
