Not all folding knives have a wire stripping function on their blades. Wire stripping is a specific feature found on some specialized tools designed specifically for that purpose. However, there are some folding knives available on the market that have additional features or multi-tools built into their handles, including wire strippers. These knives may have a specific notch or groove on the blade that can be used for stripping the insulation off wires.If you specifically need a knife with a wire stripping function, it is recommended to look for multi-tools or purpose-built wire stripping tools that offer this feature.
