Identifying horn species on a yatagan hilt

[mahratt]

Sorry for my bad english. My 5 cents. I’ll try to explain about the rhino horn. I think everyone knows that a rhino horn has a structure that is different from that of a cow horn.
The rhino horn consists of special very hard hair that has grown together. The result is a structure in which the fibers are arranged - in parallel.
This can be seen in the photographs with red arrows.
If we look at the cross section of the horn, we will see a structure that is somewhat similar to the points - these are transverse sections of hairs.

On the subject that we are discussing, we see "curls" (indicated by green arrows), which do not happen on the rhino horn. And we do not see the "points" that occur on the cross section of the rhino horn.

In addition, the rhino horn is never stratified by “scales” (indicated by a yellow arrow). But such a stratification is found on old products from cow horn ...
