Got the 10" chef's knife and 4" parer a couple days ago. The chef's knife came with a very small burr but was easily sharpened. Took a very nice edge. We'll see how long it lasts. F&F is flawless. The chef's knife weighs in at 285 grams so it's a little lighter than the ZK 52100 at 302 grams. For comparison, from top to bottom: Bob Kramer 9" chef's, ZK Damascus 10" chef's, ZK 52100 10" chef's, and ZK Essential 10" chefs.
