Maksim Enevoldsen (owner of www.japanesenaturalstones.com) taught me how to attach a handle on a knife, the good old traditional Japanese way. By heating up the tang, you can burn it very solid into the handle and then just smack it.
I feel pretty good about the fact that I never did this before and got it right the first time. And every time I use this Toyama Noborikoi 210mm Nakiri, I will be reminded smacking the handle on it myself.
