I have sharpened & used both the Kohetsu AS 240mm 5.6oz & the Hap40 240mm 8.4oz. Like the AS it is lighter nice knife for the price. The semi stainless core of the Hap40 is great steel.
Have noticed the cheap stainless clad Blue #2. The complaint is a large boxy bolster less handle. To me not a problem, you can recess the front edges, reshape the handle to your liking with some sandpaper. The Micarta material used in the handle holds up really well in a production kitchen that's why it is used so much in kitchen knives. It is 7.4oz for the 240mm same price as the 210mm 99.95 looks like a good deal to me.
