After you have used the replacement blade that is stored inside the handle, replacement blades are available to stay sharp. The Sportsmans Release Knife requires a custom cut blade.
This is the tool that other companies 'try' to duplicate. Others do not compare to this great tool made by Sportsman. This tool is great for releasing fish or for releasing you when things go bad. Will cut up to 800lb. mono. Wrist cord keeps it in quick reach. This is the one you see in all the magazine pictures! Made in Sweden.
