Got a half decent Santoku a couple of decades ago, and I`d argue your friend is right in many ways. Eye opener.
On the European side some areas/brands provides a number of levels where entry level can be quite different from the good stuff. For instance, Sabatier isn`t protected, thus anyone can label a knife Sabatier, and some Sabatier brands like Rousselon have production both in France and in Asia. Some are fully forged, some are welded. In my opinion the following would be a decent spot for a first dive into French kitchen knives +++: www.sabatier-shop.com
It would be wise to do some research before going Japanese as well, as a lot is sold by the style yet made elsewhere, but your friend would know what you should look for. Before going Japanese, do a bit of research on keeping them, sharpening, wet stones and so forth. It is a bit different to Solingen/Thiers.
