I wasn't here in the 90's, but was here pre-stroke. As Bill says, there are changes. I have noticed though that most of these have disapeared, and Bura is nearly or is the same. This is my opinion. It cannot be empircal- (i"m having a damn hard time spelling this AM) any more than say Hollow's, who has been here less time, and with any of us having only a few samples or reports to work with.
Are the reports listed here what we go by?
How many blades sold are actually used hard?
How many blades don't we hear about that do fine?
Among the hard users, how to compare?
I think Bura's edges are fine. I have noticed just the opposite of what was said in previous posts, namely, that he tempers the edge very hard and consistent and the sweet spot is large. His edges tend to be straight cuts- maybe saber cuts someone once opined, and are not like Sher's almost convex edge.
When the Kamis went very thin two years ago there were edge failures. Bura had some of these. Big deal. So did Kesar and Sanu.
I have a Bura Movie model made less than one year ago and it is outstanding. Period. Hard edge- harder than Kesar's ever were, and a sweet spot that does not end. I have a Sanu too soft on the end. Remember- there is a reason for a 'sweet spot'. Kumar's edges seem almost to go from a couple inches from tip to nearly the curve near the bolster- that's fine, but is not without it's own hazards.
Summing it up- I would buy a Bura in a heart beat. I've always liked Sher and Kumar, but you don't have to twist my arm to appreciate what is still the best- the Old Man.
