Adam, Mr. Knife Fanatic (Shaun) and I make custom handles and work with wood a lot; it's kinda like a running joke with the handle guys on the forum; sometimes we come out of our shops with blue or green hair, or whatever color we are working with. We tend to think alike in terms of what we like in knives and what we don't. It wasn't mean to be a dig on you or anyone else!
Yeah, I saw the 58 on the webpage when I went back to it. Mark may know if it's true or not, or typo or whatever.
For the bolster issue, it depends on how it is done. Some guys prefer pinned on bolsters because welding the bolster on can cause a stress area due to the heat and if the weld isn't done cleanly, can look very sloppy. Most people prefer bolsters on Western handled knives. I go back and forth with it. I don't mind a knife w/o a bolster, but a bolster won't turn me away from a knife, either.
So you are looking for a western handles knife with welded on bolster done cleanly, using a good steel and preferably with a Damascus look to it. I would for a steel other than VG-10; the vast majority of us find it to have fairly lackluster edge holding properties and it can be a pain to deburr properly. The problem is that VG-10 is the most common core metal you will find in a Damascus clad blade or a hammered blade.
Sakai Takayuki uses AEB-L in some, but there is the hardness issue. I'm not sure how the bolster is attached. Some bolsters are actually hollow and reduce the weight of the bolster area, so that is also something to consider; the bolster doesn't automatically add a lot of weight to the handle.
Here is a Tojiro Blue #2 gyuto. Only 1 review on it, customer felt it was a bit thick:http://www.chefknivestogo.com/buhaanofpe6.html
Tanaka Ironwood would also be nice, but very pricey:http://www.chefknivestogo.com/tanakaironwood.html
Shun Reserve, but out of stock:http://www.chefknivestogo.com/shunreserve1.html
Options are really limited with the criteria. If you can deal with a Wa handle, lots more options. Or if you go with a non damascus blade, but Western handle, again, a lot more options open up.
