Question on tulwar blade construction

[estcrh]

Indian horse head tulwar with wootz blade

The blade is a typical Indian scarf welded blade, but in this case, both irons used are the best quality. The hard crystalline Wootz blade has been fused to a softer, more flexible heel of Pattern Welded Damascus, with a high contrast pattern. The weld is complex, and a feat of difficult engineering according to metallurgists, but it has been beautifully achieved, with only a small lamination flaw.
