Subject: High-Status Khanjar Style Dagger: Salvaged/Recycled Blade Theory & Material

[Oiluj13]

Greetings everyone,
I am opening this standalone thread to seek the community's insights and regional expertise regarding a specific structural theory on this dagger asset.
When looking at the complete assembly, the incredible, highly precise geometric symmetry of the repoussé scabbard and the hand-chiseled bi-metal hilt clearly indicate a high-status item commissioned for military gentry or aristocracy. However, the blade flat itself appeared surprisingly plain given the intricate craftsmanship of the furniture.
To investigate the underlying metallurgy, I polished a section to a raw baseline and executed a localized control etch using a mild organic coffee solution. The etch revealed a prominent, latent vertical "tiger stripe" macro-segregation pattern running continuously beneath the sanding scratches.
This dense, columnar carbide segregation suggests a large, slow-cooled ingot steel profile. My working theory is that this blade may have originally belonged to a high-performance historical sword that was broken or damaged in the field, which was subsequently salvaged, re-tipped, and recycled into this high-tier dagger configuration by a court metalsmith.
I would love to open the floor to your opinions:
How common is the reuse and re-hilting of broken or cut-down sword blades into daggers within your respective areas of study?
Does this vertical columnar segregation matrix or the specific hilt/scabbard artwork point to a particular regional workshop or historical conflict era where this type of recycling was practiced?
Looking forward to your thoughts and any cross-references to similar salvaged pieces in your collections!
