Got to ask why aren't they hammered?
Try it on any ring no need for it to be titanium, the reason will
become obvious as you try to hold the ring to the desired size and
shape while forging it.
In knife making, you can compress the grain structure on the edge
of a blade, basically packed metal on the edge, called "edge
packing". Wouldn't this principle be similar to hammering a ring?
Packing an edge is a fairy tale the continues to rear its head in
the blacksmithing and knife makers world. You can not compress the
grain structure of metal. To do so would be to imply that you can
make it more dense by hammering. You can work harden it by forging it
but the volume will not change and the blade will get thinner
wherever you hammer it and it will stretch away from the blow
becoming wider and the crystal lattice of the metal will not become
any more dense.
Just trying to understand why people would prefer to grind than
I don’t, I like to hammer and dont really like to grind unless it is
the best way to get the desired result however using a hammer to
create a “hammered” finish on a ring is like trying to use a wrench
as a hammer, yes you can do it but the results will not be what you
