The International line of Henkels is their budget line, the German made Professional is a much better, higher priced, line.
Henkels and Wusthof both had their US headquarters in Westchester Cty. NY when I lived there, and both ran great in house sales once a year.
One time I went to Wusthof for their sale, and they had an enormous amount of Henkels knives. What? Turns out some high end retailer told Wusthof they would only take their line if Wusthof bought out their existing Henkels inventory. So Wusthof was selling Henkels Professional line of knives, blowing them out at $5 for the smaller blades, $10 for the larger blades. I bought 25 knifes, one of each including santoku, different size chef knives, carvers, steak, paring, boning, etc., plus carving sets, knife blocks, scissors, etc., plus extras. Gave extras away as gifts.
Should have bought them all and been an Ebay king. lol
Anyway, you can't go wrong with a better line from either Henkels or Wusthof. Henkels is having a Spring sale right now:
