Your praise makes me feel so good, I think I'd rather just bask in it than answer your questions. I'm not connected with Chef Talk except as a member. Somehow and for whatever reasons I became one of the knife guys, then the most active one. It's ironic in that up until the last couple of years of participating here, I've always considered myself as more of a cook than a knife "expert," and defintiely see them as a way of efficiently accomplishing cooking tasks rather than as collectors objects.
Balance:
There's no gettng around it, balance and weight are strictly matters of taste. There's no right or wrong. When I talk about "most good cutters," or my own choices, you have to look in them in that context.
Still, there are reasons why most good cutters don't see balance as an issue one way or the other and seek very light knives.
That you say the big thing about balance is the security of your grip, and that you find the Ikon very comfortable raises questions about your grip and grip mechanics. You don't need to hold the knife any tighter or more securely than is necessary to keep it from falling out of your grasp. It shouldn't feel secure -- but not feel insecure either. It shouldn't be an issue.
Here's a picture of my grip taken from underneath:
I think you can see that my back three fingers aren't wrapped all the way around the bottom and that they're not applying enough force to the bottom of the handle, to push the top hard into my palm.
This works for me in a couple of ways. It keeps my knuckles well off the board, which is a very good thing indeed. It also allows my pinch to focus as a pivot point allowing the knife a little bit of extra up and down action.
It's a very versatile grip which will let you use almost any chef's knife comfortably, at least so long as it's sharp. The greatest weakness of the "soft pinch grip" is its lack of power.
You're sending your knives to a good pro sharpener every four weeks -- so, unless you're a working pro, they should be very sharp and well maintained. On the other hand, if you're turning five full shifts a week doing prep and on the line, that's not nearly enough sharpening. That would go a long way to explaining why you're having the balance issue. I should have asked before, but forgot.
There's a lot of guess in this, but I think your identifying weight and handle issues as "balance," that you're also more than usually sensitive to handle shape -- possibly as a function of your grip.
Misono UX-10:
Outside of styling, the most striking factor of this knife is its agility.
It's one of the first really high-zoot Japanese made yo-knives. It was designed to blow Shun and Global out of the water and it certainly did. However, it's been around for a long time and has plenty of competition.
My feeling is that the knife is too streamlined -- that it's too narrow between spine and heel; and that it's overpriced compared to the MAC Pro and Masamoto VG which are just as good. It does have a GREAT handle, though.
Misono uses a secret Swedish alloy -- almost certainly 19C27 -- hardened to somewhere around 59RCH. The knives can be made very sharp and hold an edge quite well. But it's nothing remarkable. It's certainly no better than either the MAC Pro or the Masamoto VG. Some people complain that it's hard to move a lot of metal on the knife and it's consequently difficult to re-profile. I've thinned a couple and didn't have that experience, but don't discount it either. Probably not an issue for you, since you don't sharpen your own knives.
Considering how sensitive you are to "feel," I wouldn't consider ordering without at least holding one; no matter who recommended it. That is at least not until you've identified those things which make knives feel or good or bad.
MAC Pro:
I recommend MAC Pros to more people more often than any other knife. It's the easiest transition into high-end western style Japanese knives because the blades are so stiff and the handle is so incredibly good. It also has a very nice edge profile -- if not quite as nice as the Masamoto.
Best handle in the business.
MAC is another company that doesn't release the identity of the alloys it uses. I used to think VG-5 was a pretty strong guess, but it turned out that I was mixing up two Takefu stainless alloy series and a lot of the "feedback" I was getting had actually originated with me. Now I think VG-1 is more likely than VG-5, but not incredibly sure it's either. It doesn't really matter. The Pro has very good edge characteristics. Every bit as good as the UX-10 and the MAC VG.
Other Japanese Knives:
After trying out the MAC and one or two other Japanese made knives we should get a feeling for whether their lightness takes care of the balance problem. Ditto for the combination of the MAC handle and weight.
If it turns out you can be confident enough to buy a knife on line we can start talking about a few other high-end possibilities like the Hattori FH, Kikuichi TKC, and the already mentioned Masamoto VG.
It runs agains my generic advice, but until we've nailed down those factors which make a knife feel unacceptable to you it doesn't make sense to buy without at least waving the knife around a little. My guess is that you're just the wrong guy for a heavy German -- but let's wait for some confirmation. In the meantime, I'm predicting great thing from your MAC Pro test.
And, if worst comes to worst, you know you like the Ikon. That's not a bad thing by any means.
