Back to the OP and the wonderful spoon #1 that he carved. Quick study. I think I can make a carver out of him yet.
Two things:
1. The neck between the bowl and the handle should not be thinned. Looks good but that's a stress point with heavy mixing.
Stuff like bread, scones, pasta and pizza doughs. I stir with the handle. The bowl end would break my wrist.
The contours of the handle can be smoothed with the crooked knife, shallow, dragging, slicing cuts.
2. Thin the rim of the bowl void, from the inside. That makes the bowl look bigger and thinner. Yeah, it's a fake, an illusion.
Everybody should do it.
