This Kanna is a valuable asset for anybody working with wood. It is a Kanna used for making a 45 degrees edge. Wood used in areas where it can be touched (such as exposed posts, furniture, etc) needs to have it edge taken off for saftey reasons. I believe it is called a chamfering plane in English.
It looks a little different from other Kannas, the screws are to blame, but the system is quite simple. It is a small Hira Kanna fitted into a jig. The adjustment screws allow the shaving width to be set, helping create a clean, even surface.
The smaller Hira Kanna can be easily taken out. It is necessay to take out the Kanna from the jig to remove the blade. When removing the blade, place a piece of wood on the hammering area. This is to make sure the “step” part is not accidently hammered.
Why is there a metal plate on the underside of the Kanna? When in use, only a narrow width of the Kanna is used. This means an uneven bottom surface is unavoidable. The metal plate helps prevent this from happening.
This Kanna can be used for a while until sharpening is required. When the blade starts to feel a little dull, simply slide the Kanna a little.
Here you can see (a little difficult to tell, sorry) the difference. The left picture is before and right is after. Usually, only a few strokes of the Kanna is all that is required.
This Kanna is fun to use. Unlike the other Kannas, it doesn’t require as much skills to get clean results. Just becareful of tearouts.
