I sure was! Without this cutter I was missing the one needed cutter for completing the set. I have an older King Cutter and the fit is as good as the original blade set. I can now do the thick slicing I wanted.
Works great on the King Kutter giving clean cuts on vegetables & fruits(firm). Easy to clean and easier to use. Easy to get finger cuts. Lock this up around visitors if you want to keep it. Not a loaner to even family.
