I think the point is, since it is a mid tech knife, but done by hand, there may be variations from blade to blade. Mine was definitely thick on the shoulders.
I have one of the first 270mm ITK's and I think it compares most favorably to my Suisin Inox Honyaki 270. The blade profile is almost identical. However, the ITK is just a tad thicker. Its by no means fatty though. Compared to something like a Shigefusa, or a Watanabe or a Carter the ITK is a light saber.
The thing alot of people don't get about the DT ITK is you gotta put it to the stones to make it sing. While I wouldn't say the edge that Hoss puts on his knives is as bad as the edge you would get with an Aritsugu Type A. I will say that if you buy an Aritsugu type A and don't properly establish the edges out of the box then you will NEVER see why the Type A is so highly regarded.
After I worked over the edge on my ITK it really began to sing!
Thank you for the suggestions and discussion all. Unfortunately it just makes me want to get multiple knives now to compare and contrast.
At least there seems to be a decent resale market among the knife nuts.
I just tried my 270 DT ITK in my 270 Suisin Honyaki Gyuto Saya that came with the knife and it fit fine. The Suisin is a snug fit with a little friction in the last inch or two shy of pushing it home in the saya and the ITK has only a little more friction. Its snugger--but I wouldn't say its tight in the saya.
As far as the DT ITK goes, there is too much variation from one batch to the next for you to have a realistic expectation. I would suggest that you get on the list to pre-order, but ask Mark not to ship it until he sends you a picture of the actual knife and its dimensions. You can cancel if it isn't what you want.
I have a western 240mm:
heel to tip - 249mm
edge to spine at heel - 54mm
weight - 217g
It has a nice distal taper and is reasonably thin behind the edge. The profile was a surprise when I got it. I like the edge, but it is too tall near the tip. It looks more like a big santoku than my ideal gyuto.
My first DT ITK was a wa 240. I returned it because the edge was overground at 3-4 cm from the tip. It was bad enough that I cant fix it. My western 240 is also overground, but not nearly as bad. My main reason for getting the ITK was to evaluate Devin's steel to see if i want to order a custom. It takes to long to get another ITK, so I'm going to customize this one by regrinding the profile of the spine and re-shaping the edge a little to even up the overgrind.
I haven't seen anything quite like the DTITK. Stainless, hard at 61+ hrc, nice thin tip (similar to my HD and IT) and fairly hefty heel with excellent fit and finish and a stabilized handle... I would go with a Yoshihiro. Jon stocks these. They are pretty nice although the spine and choil are not rounded, if I remember correctly. If you don't mind thin, I'd go with KonHD, my personal favorite at the moment (along with my DTITK).
It is true there is some variation in the DTITK's and the wa version doesn't seem to quite have the same profile as the western. I've seen three 270mm wa DTITK's. Of the three, one had a significant overgrind near the tip which Devin promptly addressed. The first batch was thicker than subsequent batches.
Here are some pics of a Carbonext, if you would ever consider one.
Hmm, I was hoping those would be bigger, my first time posting pics. Any idea how to make them bigger?
