The process of shaping the bamboo knife was much simpler than the stone axe. It took him only half an hour to grind one side of the front half of the bamboo piece into a beveled blade. It was a double-beveled edge, with the sharpest point right in the center.
The first round of sharpening didn't need to be too fine; just creating a rough outline was enough.
For the second round of fine sharpening, he needed to find a stone with a relatively less coarse surface to act like sandpaper, slowly grinding the blade's surface until it was smooth.
「Another half hour passed.」
A decent-looking bamboo knife was born.
He even made a point to adjust the way the bark was wrapped around the handle. He flattened the originally twisted bark and wound it around flat, layer by layer, much like the grip of a badminton racket.
This wrapping method made the grip feel steadier and smoother, which helped with power delivery when swinging the knife.
