Eh maybe. There is a reason they were replaced in the manner that they were in many cultures. For example, along the Great Lakes we see that many cultures begin to replace stone points and knives with copper elements scrapped from copper trade goods as soon as they had access to the trade goods. Copper was easier to work with, easier to rework, and simply just sturdier than a stone tool. Once the British and French started trading copper pots we suddenly see that everyone is obtaining these pots and dismantling them to use the copper for tools. Parts of the rim would become knives or fishing hooks, for example. I'm generalizing for a bit, but the biggest reason people went away from stone tools is that they can be finicky to work with. I flintknap in my free time, and it can be VERY frustrating to spend an hour on a point only to have it break because I hit in incorrectly when trying to break a flake off.
