We do not offer blade swaps for different styles, configurations, etc.
You may buy a replacement blade in the exact same style for a fee, but unfortunately interchanging styles is not a service we provide at our facilities. We do not add serrations to blades.
We do not swap styles because the handle and blade are adjusted to work in that exact configuration. This varies from knife to knife. Even if the blades are identical in look but vary in color or serration, the base of the blade and the internals are adjusted and tuned for that particular handle. Swapping them out can cause problems.
