Hi
Nice blade....... you know there it could be an english blade...
have you heard of shear steel........ some of this shear can really reallly have a lovely wootzy look.....
here is what i mean...... Ray Richards forged out some old saw mill blades into knives.... and then etched them..........
Look at the 2nd knife he made ( about the middle of the post )....... see the swirly pattern on that shear steel.......

it maybe that this blade might have a hint of that......... who knows.... or maybe its just the rust that made a pattern.. ??? hard to tell with photos
