How to tune and repair a Japanese wooden hand plane (Kanna)?

[@PhilNPrice]

I just bought an old (used) plane from Japan. The surface where the blade rests on the dai is very curved…not warped, but a smooth curve so that a flat blade only touches along a line down the middle. I have never seen that before. I think the only way it could work is with a blade that is also curved. But the plane is clearly well used and was even repaired at least once, so obviously someone thought it was worth putting a lot of work into. I can’t figure it out. The only thing I can think of is to try to cut out the curved part and replace it. It is not the same thing you did to your plane in this video but this video gives me confidence that I can do it. Precision and patience are not my strongest suits but with some discipline I think I can succeed. Thanks for showing the way.

I'd love to see a video comparing the $300 blue steel plane with this one

I want to see the DIY PROJECT where this 300 USD hand plane was used - that what is REALLY interesting 😀

Blade standing on waterstone means that it is flat

How did the more expensive plane do??

[@thomasnourse7506]

How did you order the good plane and from where? I bought a $120 plane and the blade was chipped and nicked after 1 pass on a clean maple tabletop.

You don't need to go to a ceramic stone to get shavings of this quality. If you just finish on 1000 or so diamond stone and directly go on to a green compound strop you would get equally good shavings on any planes. My experience with cheaper blades is that freehand sharpen with a convex grind makes them quite a bit more durable (Yes I realize you need training to do that). That said, amazing job with a 30 dollar item.

Claims to not be a "woodworking person." Has a bunch of sharpening stones & does the blade trick like it ain't no thing.

I did it myself. I used Woodglut woodworking plans for this.
