It is little thicker at the spine than Ginga, bottom 1/3 of blade is very thin. I put my Gesshin Ginga stainless side by side the Ikazuchi is thinner behind the edge.
Don't know what is going on not a tech dude load pics from google chrome. Insert, paste on thread they load. Both threads I can see all the pictures but no else can??
Any chance you could weigh it? (Manufacturer's spec are often off a lot) And give an idea of the balance point?
for what its worth, the weight we list on the site, is an average of a few different blades, which is usually more accurate. Where it gets off is when the next batch they send is different (in the case of kochi, for example, where we have constantly provided feedback in order to improve what we were doing). In this case, the weight will not be changing for a wide variety of reasons.
