Cut marks left by bladed tools can provide useful information in various fields. They vary depending on the tool and material used, and can help identify weapons used in crimes. Cut marks can also be found in everyday objects, providing insight into their creation.
Cut marks are marks left by a bladed tool such as an axe, saw, or knife. Often, the cut marks form a very distinct pattern, which can be useful in many ways. In home design, markings are sometimes used to create a feel of hand-carved planking and may be left intact on antique furniture to emphasize that the furniture was handcrafted. In criminology, brands are used to learn more about weapons used to commit a crime, and sometimes these brands are so unique that they’re almost like fingerprints, becoming a key aspect of a case.
Any bladed tool will leave some sort of mark as it cuts through the material. The type of cut mark created varies depending on factors such as the material the tool is made from, the type of blade, the weight behind the blade, and how the blade is used. For those familiar with the studio, these little markers can tell a fascinating story about a series of events and can be used to reenact a scene.
In criminology, for example, cut marks can be used to narrow down the type of weapon used to commit a crime. Knives, axes, saws and other weapons all leave unique marks. Handsaws and chainsaws behave differently, while serrations of different widths leave distinctly different traces. Someone who hesitated might leave a false start, a partial cut next to the completed cut that can be used to generate even more information about the weapon being used.
On television, it seems that criminal investigators always discover cut marks and miraculously trace them to specific weapons. In reality, this doesn’t happen very often, but sometimes it does, thanks to the efforts of researchers who have dedicated their careers to studying these brands. More frequently, forensic examiners generate a list of weapons that could potentially have been used, giving investigators more work to work with.
While it helps to have years of experience studying kerfing, you can sometimes find examples around the house and garden that might be interesting. You may also have noticed that different types of saw behave differently when you use them, and if you examine the ends of cut wood after you saw them, you can see the cut marks you left behind, often along with false starts, if you aren’t familiar. with the use of a saw.
