Indian wotsit -Keratch?

i think you may have meant 'acid etched'. A pattern of resist is transferred to the object, usually repeating along the object, which is then dipped in acid eating into the bare parts and not the resist coated ones.



In true pattern welding the pattern goes all the way thru. I'll polish a patch and find out. Hand rasping to hide an etched pattern rather than just using a power grinder seems a bit unusual. Even a bit of hand sanding would eliminate a botched etch better.

Those blank spots on the blade are curious.
Usually I see this pooled, or bullseye pattern used in contemporary work, but this isn't contemporary I think.

I suspect the 'blank spots' aren't, it's just artifacts from my converting to greyscale to emphasize the patterning and 'optimizing' the photo to HDR. I'll take better ones eventually when it arrives.

Thanks, Kronckew
Yes, I wanted to say it

There is no pattern distortion on the bevels of the blade.
With pattern welding, there should be distortions of the pattern in these places.
