The two starting blocks were composed of a total of 13 individual plates :
M = MILD STEEL, inner at 1/8", outer at 3/16"
I = WROUGHT IRON, 1/4"
L = L-6 (nickel mid carbon alloy), 1/16"
H = 1095, 1/8"
All pieces at 1" wide x 6" long
After welding to blocks, each was drawn to a rod roughly 70 cm long x 12 cm.
Next each was facetted to octagon, then given three sets of twists (alternating with straight sections).
The two cores were forged square, and fitted to two pieces of 1045 (coil spring) and prepared for the next stage.

* There is a lot of confusion on language here.
I use 'pattern weld' the way I first learned the term - as the archaeological definition :
Two or more layered rods, twisted, which form the core of the blade.
The starting stacks combine separate low and higher carbon plates, usually as low layer count.
The twists will alternate and match with clockwise and counter-clockwise direction, often including straight sections.
Most commonly a separate mid to high carbon rod is welded to each side of the cores to form the actual cutting edge.
The method was used primarily in Saxon and Norse blades, known samples ranging roughly from about 400 - 1000 AD. The ultimate example is the complex blade from the Sutton Hoo burial (a royal status object, consisting of eight individual cores, mirrored in pairs side to side and top to bottom. It was most likely created in modern day north Germany or south Denmark, about 600 - 625 AD.)
