A few years ago, I purchased an old Kanna from a flea market on the West Coast.

It was in rough shape and had clearly seen a great deal of use…it hadn’t spent it’s life sitting around.

The steel is incredible. Even though it’s “dull” and has been sitting up for a long time, there is still significantly formidable edge on it. Looking closely at it, it appears to be folded steel or at the very least traditionally hand crafted Japanese steel.

I’ve sent some emails over the last few years to some folks who should know, regarding the pedigree of this particular Kanna, but never got any reply. There is a clear marking on it, but I have yet to properly identify the characters.

I’m really just curious. The tool has a sort of transcendental presence to it…

I refuse to sharpen it until I’m sure I can do it properly… It does look like it’s been sharpened according to traditional methods (maintaining the concave side of the blade)...

I really just want to know more about it and was hoping some of you cats might have some insight.

Thanks

I am not able to identify your blade, but you are right about it being well used. Traditional blades are made with a hard steel back/cutting edge, laminated to a softer steel or iron layer. The hard steel layer only extends roughly halfway the length of the blade. On your blade, it appears that the hard steel layer is almost completely worn away. Sharpening the bevel will show the two layers more distinctly.

There are plenty of websites devoted to Japanese tools. Try web searching for “Japanese kanna setup”, or “Japanese plane setup”. Toshio Odate’s book on”Japanese Woodworkng Tools”, is a good place to start if you are looking for a book.
