The handle attaches to the cross brace with a mortice and tenon. The tenon is purposely cut a little loose and the shoulder is curved to allow the handle to pivot slightly as the blade is tensioned.
I just use the width of the mortice chisel to mark the width of the tenon.
I use dividers to mark the curve of the shoulder, with a matching curve on the handle.
Cut on the waste side of the knife line.
Cutting the curve is a little trickier. Rough with the saw.
Then trim with a chisel.
Again, the tenon is cut a little short to allow some movement.
Next time I will show you how I cut the matching mortice in the handle.
