The guard of a folding knife can vary depending on the design and construction of the knife. In some folding knives, the guard may be a fixed part of the handle and not removable. This is typically the case with knives that have a one-piece construction or a handle that is molded around the guard.However, there are folding knives that have removable guards. These knives often have a design where the guard is a separate piece that can be taken off or disassembled for cleaning, maintenance, or customization. This is commonly seen in certain tactical or survival knives where the guard may serve additional functions such as a handguard or a tool attachment point.It is important to note that not all folding knives have removable guards, so it is best to check the specific model and design of the knife in question to determine if the guard is removable or not.
