350 words needed to answer these 4 questions (not including words of the question itself) 1. Purchase a cheap candle from a dollar store. Press a chisel into the wax. Look at the class and individual characteristics of the tool. The class characteristics include the width and depth of the chisel and the individual characteristics include the many minute scratches you can see on the chisel that are now transferred to the wax. This is an impressed mark. Scrape the chisel down the wax. This is a striated tool mark. Again note the class and individual characteristics. 2. Dig a chisel into the wax. Observe the three-dimensional tool mark and the class and individual characteristics. 3. Get a pair of pliers and grip the candle hard enough to leave a mark on a fresh bit of wax. Identify the class and individual characteristics. 4. Go to a tool store and look at new tools. Examine the heads of several new hammers or the tips of several new chisels. Notice that they still contain many minute scratches that could be individualizing despite the fact that they have never been used
