another twist-core

[DaveS]

Here is another twist-core i picked up a few years back. This is the
second one i have seen with an offset garuda style pommel. The blade is
19 inches long, 25 inches overall. The pattern is exactly the same on both
sides. No scabbard. Some patterns like this seem to be etched in,while
others seem to look like threads of nickel like an Indo-kris. has anyone ever
figured out how these are done????.......Dave.

Actually both are the same, the first ones are topographically etched, the other not. Newbold (1839) describes topographical etching of kerisses from Malay Peninsula:

"Place on the blade a mixture of boiled rice, sulphur, and salt beat together, first taking the precaution to cover the edges of the weapon with a thin coat of virgin wax. After this has remained on seven days, the damask will have risen to the surface; (...)"

Also the Madurese blades are sometimes topographically etched.

Note only a fine blade, but a rare hilt style to boot!

Congrats!

Actually this makes sense. This is an old technique and is still used today to deeply etch metals.

Oh yes and congratulations (grumble, grumble ). I am so happy for you getting such a nice blade (grumble, grumble ).

I was fairly sure that the first kind of pattern was done with a deep
acid etch, but the second type with the threads of nickel has to be con-
structed the same way as any type of Indonesian pamor. I can't see that
it could be done any other way.........Dave

I really like this Kris, with the not too common to me, a 3 waved blade.
As I understood, a true taluseko

oncemore -

both kinds (actually there is only one kind) are done like a normal Pamor from Indonesia or Malay Peninsula, using iron with some nickel % or some other element, which would react differently with acid.

The difference here is only the method of etching - topographical (like described by Newbold - a strong etch) or a normal one.

Gustav: A deep topographical acid etch to create a twist pattern is
completly different than a manipulation of a bar of iron and nickel
to create a desired pattern. The twist core kris i posted last week
was done in an entirely different way to get that pattern, then it
was etched to bring that pattern out. A deep etch using acid and
some kind of resist is the same as seen on some swords and
"damascus" gun barrels.........Dave.
