I got this knife about a month ago and liked it right away, but it needed work OOTB. Factory edge was piss poor so the first thing I did was sharpen it. I established a 2mm edge on the right side then a <1mm edge on the left as it is asymmetric 70/30. I also eased the spine and choil and polished the blade a little before sharpening. It took a very nice edge quite easily on Gesshin 400, a red 1k and a King 6k followed by cardboard and news paper strop.
It is a great working knife weighing in at c-hair over 8oz on my kitchen scale. That is with the handle I made from flame maple and blue dyed cascara and a mosaic I made. New this costs < $200 and with an Amazon coupon it was $159 shipped + I got coupons from Yoshihiro for future purchases. Because they were back ordered one day he sent me a bottle of camellia oil as consolation. Great customer service. Oh and this knife came with a saya too so good deal all around.
I like the flattish profile - it's the longest 270mm knife I own - a good 1/2" longer than my Kono HD and Hiro AS. It's got a nice distal taper - I measured on the spine and 2mm behind the cutting edge - handle: .115"/.036", mid point: .10"/.030", tip: .021"/.020". For a knife this long it feels light and is nimble in the hand. It will rock chop further up the blade, but let the pictures do the talking.
