Just want to share, my Konosuke HD 240 Wa-Sujihiki arrived fro CKTG today. Funny thing is there was not pin hole in the saya to plug the pin. But the knife was really sharp OOTB. It push cut paper effortlessly and is very light. BTW I bought this knife after reading all the favourable comment by BDL. Know I'm going to enjoy using it. Guess I don't need to put it to the stone for the time being. BTW wondering where should I drill the hole for the pin, anybody willing to share. Thank you.
