well, i hope we can agree that your knife has seen a lot of honest work.
I would advise you to consider buying .. more knives. See, the reason why you like that knife is, probably, that it's made of a good steel. However the shape is not great for most kitchen work.
Obviously i'm speculating now, but i think you are comparing your good-steel-bad-shape knife to bad-steel-good-shape knives, instead you should get yourself a good-steel-good-shape knife.
There's a clear distinction between european knifemakers and japanese knifemakers. EU knives tend to be more practical, we have far fewer purpose-specific designs, and the metal tends to favour easy sharpening, long life and ease of maintenance.
Japanese knives are the opposite; they have very unusual shapes that are often for just one specific purpose, and use extreme metals that are really bad for anything outside of their one purpose. To elaborate on that, you can buy knives that are really brittle and will chip or break if hitting a bone, and that will rust within a day if left uncleaned after cutting a tomato. On the other hand, they will come with a edge hardness that is in another world compared to a german knife.
Even in a - modern - sushi bar, there's always a hygiplast:
because those things are a workhorse. They sharpen with one pull of the sharpening tool and you can yeet them in the sink or in the dishwasher without thinking twice.
And they cost $10 - ten bux.
They also suck if you are trying to make sashimi. We have no such concept in europe, food is for eating, not for art, who cares cut is cut, need more cut not less cut.
There absolutely are european knifemakers who make high HRC knives, but yeah, Japanese knives are all about that sharpness. The japanese are happy to have to own a set of whetstones are spending time maintaining their knives, so obviously their product range is aimed more towards that kind of tool use.
There's really nothing that compares to a HRC 64 knife. A typical HRC value for a EU knife will be between 52 and 56 which is butter when compared. HRC 64 is like a laser, it will cut your finger before you can get a feeling "if the blade is sharp" and it will glide through meat like through air. Those things are not easy to maintain, they are delicate, they will rust with water and oxidate with anything acidic, they are brittle and need to be oiled because even oxygen and moisture will ruin them. There must be a specific need for you as a chef to own such a tool, to justify having to deal with the maintenance.
As i imagine you are not making sushi, consider investing into a Aogami n2 or Shirogami n2 Gyuto knife, or even a Aogami Super, they are super-modern steel types, far easier to own (although maintenance is still required), such as this:

$350 Shirogami n2 semi-stainless (chromium based alloy) gyuto with esthetic decoration + polish:
just a final, important note: a $200+ knife is for life. Im not telling you to spend a grand, but in the end if it's 200 or 400 it's irrelevant, 30 years from now you will still be using it.
