So, I've used this for a while. First impressions, the 240 Kagekiyo is a good bit shorter than the 240 Konosuke Funayuki. Wasn't expecting that. The white 2 is probably exactly the same size as my previous Blue 1 Kagekiyo, but it's been a while since I owned that. The Kono Funayuki is a little taller, too. Edge retention between the two is about a wash, despite the steel difference (White 2 vs White 1). The Kagekiyo is a good bit thinner behind the edge and at the tip, and is a good bit thinner throughout the section of the knife. The Kagekiyo definitely cuts better, and feels great, being wonderfully balanced. The magnetic saya for the Kagekiyp is great. The handle is perfect on the Kag, and I love the plain lacquer. The Kono has very nice finishing, but the Kagekiyo is perfect. They are both nice knives, but the Kagekiyo is just better all-around. I'd prefer it if the Kag were a little longer and a little taller, but there's not much in it. Great knife.
