My early FS-era HAK is custom sized. I have small fingers and the more common sized hands won't fit any better than Cinderella's sisters trying on her shoe. These days, I don't know. A pile like that pictured could have easily been the most common size - why make lots of something that doesn't sell?
From what I understand of the manufacturing technique, they are lazer cut from sheets on an automated CNC machine. The programmer probably set it up to do one size to minimize waste. It's what we do with the turret press at work - many parts from one sheet, and usually all the same size.
S30V has been accused of being brittle in some early production of other blades, but I've not heard it was a problem with HAK's. Polishing S30V doesn't seem to have caught on with knifemakers - it apparently has a dull appearance with some orange peel and it's not worth it. Considering the original application inherent in the name, it could be counter-productive.
I haven't seen much success in ordering custom grinds, and make no assurances. The standard model seems to be available even these days, and for someone with the patience to navigate the ordering system, knives seemed to be shipped regularly, as reported by them in (other forum) posts.
There are competitive designs out there, but like any design and it's brand, how the buying public percieves the value is all important. There does seem to be two points of agreement for most - it's a darn shame that HAK has a left a bad impression on the market, but the knife itself does what it's designed to do, if you are comfortable with it.
I would definitely include it on my battle rattle, as many have, and still carry it when I need a utility blade with convenient access and little chance of loss - hiking, hunting, tree stand, etc. I like to tell how it dresses deer out, but fortune has stacked about 6 blades ahead of it. Wish me luck.
