Folding knives can be suitable for cutting hard objects, depending on the blade material, design, and intended use. Some folding knives are specifically designed for heavy-duty tasks and are equipped with durable blades made from high-quality materials such as stainless steel, carbon steel, or specialized alloys.However, it is important to note that folding knives generally have limitations compared to fixed-blade knives when it comes to cutting hard objects. The folding mechanism introduces a potential weak point at the pivot, which can make the knife less suitable for heavy prying or excessive force on the blade. Applying excessive force or using a folding knife for tasks beyond its intended use can potentially damage the knife, compromise its structural integrity, or even cause injury.If you anticipate regularly cutting hard objects or engaging in heavy-duty tasks, it might be more suitable to consider a fixed-blade knife, which generally offers greater strength, durability, and resistance to torque or lateral stress.Ultimately, it is essential to select a knife that is appropriate for the specific task at hand and ensure that it is used within its intended limitations to maintain safety and maximize its lifespan.
