The drawer front on this table is curved, and it is worked out of a solid block rather than bent to shape.
A bow-fronted drawer has a problem the rest of the chest does not: its front must follow the curve of the carcass exactly, while the drawer box behind it is a straight-sided rectangle that has to run cleanly in and out. The two things meet at the front, and the join has to be strong enough to be pulled on every day.
The dependable way to do it is to start with a front thicker than it needs to be - thick enough that the whole curve lies inside the block - and cut the curve out of it. The face is worked to the outside radius, the back to the inside radius, and the drawer sides are jointed into the solid ends that remain, which are full thickness and take a joint properly.
It wastes a lot of timber, and it takes a long time.
What it produces is a curved drawer front that is one piece of solid teak with no glue line in it, and joints at both ends cut into full-thickness material - which is what allows it to be carved over its whole face afterwards without weakening anything.
