Wootz again.

I have other source for wootz(the real one) NH

Before forging this bar, look out my own steel cake.
Some blade made of this little raw ignot
Same blade different sides

Edge is too brittle, maybe new heat treatment help with this prob or addmixes causes that, there is lot of V, Cr, Co, W...

Pattern welded blade is result of practising, C 1%, F52, bandsaw.




And main thing HN Wootz, tree blades,




one finished with kingebony handle, slice moosehorn, own casted bronze with steelwire chips.
