First, I am not a maker. I like looking around over here as I really appreciate the craftsmanship I see.
But I do cook. And I mean a lot! When we have company, it isn't unusual for me to stand at the counter and cut up food for a solid hour. An the average, I use my larger kitchen chef knives for meal prep for about 10 meals a week.
The knife is quite nice. But if I were to buy it, I would have a couple of tweaks I would like to see. Remember... this is just an opinion!
First, I like the back side of the blade (the heel?) facing the handle to have a thicker and more rounded profile. If my hand slips forward, then it doesn't hit a square, and possibly sharp edge. This is pretty easy to do when your hands are wet.
Second, I would drop the butt of the handle a bit, starting at about half way down the handle. It makes kind of a crook pattern when you do this.

Dropping the heel of the handle makes the knife much easier to use for routine chopping. I use my chef's knife for a lot of chopping, so the dropped handle heel tilts back my wrist to a better position when I rock the knife back and forth on the board. Hold the knife in front of you and grasp the blade with your left hand which will tilt your wrist slightly to the left. When you then grasp the knife with your right hand, your hand should sit on the handle and tilt slightly to the right. With a straight handle, you either move your hand a bit off the handle to do this, or your wrist is parallel to your cutting surface. After a few pounds of potatoes, onions, carrots, etc., for a really large roast your hands will be pretty tired.
Last, for me, a bit less sweep on the blade would make it easier to slice and control with that much sweep it appears that you would have the handle of the knife high off the board when using the tip. This makes you have less control of the knife, but also increases motion needed to use it. It might make it uncomfortable to use the tip of the knife for routine slicing.
The trick on that is to find that magic point where there is enough sweep to rock the knife easily back and forth over your material to be cut, but no so much you have a large amount of hand motion needed to use the length of the blade when doing so. That's why you don't see commercially made chef's knives with a large sweep design.
I find that when I do use my chef's knife for slicing that less sweep makes it easier to use the length of the blade as well.
All that being said, the knife is gorgeous and I am sure whomever gets it will be thrilled. I would be!
