Question on tulwar blade construction

[estcrh]

Cousin of the tulwar known as kirach or karach and it is characterized by the slightly down curving blade with the edge on the concave side and the down curving spine with a false edge.

The blade is 32 inches long with 10 inches false edge forged from good Indian Damascus wootz (crystaline) steel, marked with armory marks on both sides as well as on the spine and made in the construction known as scarf welding. Scarf welding was done by welding two ingots of steel in or around the upper third part of the blade, in order to provide the blade with both strength and flexibility. It was a common technique since many centuries and found on both Indian and European quality swords. Here the welding point is clearly seen in the close ups as a darker semicircle.
