Allegedly, the " oatmeal" structure was considered to be beneficial to the sword owner for some sacral reasons..
Further, the author stated that the frequently found reverse position of the slabs ( "oatmeal" inside) is a sure sign of late replacement.

There is an alternative version. In Iran and India, where walrus tusks were valued higher than elephant fangs, the masters tried to demonstrate the inner part of the dentin. Because the inner part of the tusk indicates that it belonged to the walrus. In the Caucasus, they did the opposite, demonstrated the external part. Because there were no walrus tusks in short supply.
