There is a huge price difference between the 210, 240 and 270mm Sugimoto wa handled gyuto's for some reason. It is known that many Japanese knives do not come with a polished fully sharpened edge, so that is normal. The handles on lower end knives can use some TLC with sandpaper to smooth them out. Again, this is often the case especially with less expensive knives.
I would see if Mark can pop the handle off and flip it around or exchange it for an oval one for you. Some D shaped handles can be brought to an oval shape with files and sandpaper pretty easily. If Mark doesn't have extra plain oval handles, I probably have a few kicking around my shop I can send out.
The ITK I had tended to wedge a bit, maybe try the DP Wa Gyuto or the Sugimoto instead?
