Found Objects as Blades — Are They Effective?

Choosing the Right Object

When selecting a found object to use as a blade, consider its material strength, durability, and potential for sharpening. A sturdy piece of bone, antler, or a well-made stone tool can be a reliable option. For instance, a straight branch of hardwood like oak or maple can be sharpened to a decent edge, but it will likely be brittle and prone to breakage. On the other hand, a piece of obsidian or flint can be knapped into a sharp edge with relative ease, but its glassy surface may be more difficult to sharpen.

Knapping for Effectiveness

To maximize the effectiveness of a found object as a blade, it’s essential to knap it into a sharp, angled edge. This process involves carefully striking the object with a harder stone to remove small flakes and reveal a sharp edge. The goal is to create a 20-30° angle, which will provide a razor-sharp cutting surface. To do this, start by identifying the object’s natural edge, then use a pressure flaker or a soft hammer to remove small flakes and create a bevel. Continue this process until you achieve the desired angle and edge sharpness.

Alternative Uses and Safety Precautions

While a found object can serve as a makeshift blade, it’s crucial to remember that it may not be as effective or safe as a purpose-made tool. Be cautious when using these makeshift blades, as they can be prone to breaking or slipping. Consider using alternative methods, such as using a piece of bark as a makeshift scraper or a sturdy stick as a digging tool. Additionally, always prioritize safety when working with sharp objects, and be mindful of the risk of injury or infection.
