Thank you!

I recently bought the high speed steel paring knife (Couteau a Parer) from Vergez Blanchard but it's no longer sharp, taking me ages to skive down the leather edge. I used a King Deluxe sharpening stone made for Makita but that stone is no longer in my possession and I am not sure what to replace it with as it seems to be out of production. What sharpening stone would you recommend for such a tool?
