This is a Lefever H refinished by Breck Gorman that demonstrates 2 end-on rods, which is a quite different "lopin" from Twist (alternees of iron and steel simply layered then mechanically rolled into rods, which BTW were not "twisted" before being wrapped around the mandrel.) Steve Culver believes that the "mushrooming" of the surface was from hammering.

Doesn't really matter as in my tensile testing study the Damascus-Twist specimens had about the same strength as the Twist, and both slightly less than Crolle Damascus

The H grade I saw had doll's head extension. That one looks like a DS, no?
