What Glestain do you have? Glestain knives are pretty awesome. I have a Glestain 210 mm Chef’s knife.
As for the CCK KF1303, do you know why/where your hand hurt? One possible reason is that many Chinese knives have a very wide blade which may induce a poor posture. I cannot find a good picture, but let’s use this as an example:

Ideally, the elbow between the forearm and the arm should form an angle a little greater than 90o. In another word, the forearm should be slightly pointing downward. However, if you have a high kitchen counter, and/or a thick cutting board, and combine with a wide blade Chinese chef knife, then you may end up with a poor ergonomic situation.
