This Parang has a blade made from a Maraging Steel (martensitic aging) called ULTRAFORT.It is used for the armoring of Limousines and other vehicles against bomb attacks and stuff like that.It is not heat treated normally(furnace, oil quench, tempering)it is hold 7 Hours in 570 degrees. in that time it developes and excretes carbides which bring the steel up to 61 HRC. It came out like it get in, no bending and warping.
Just a few carbon spots from the forging process, the steel has a carbon amount not worth mention it( less than 0.10 %).
This is no material with great edge holding ability but it is extremely tough.Whacking through an 10mm mild steel rod with no damage or loss of sharpeness to the convex edge, which was ground to 0,4 mm bevor sharpening.
Forging was no fun, but grinding and finishing was easy like a normal tool steel.
Blade Length is 375 mm, width: tapers from 6mm down to 3,3mm.
Handle and sheath are made from the same Padouk root, Ferrule and fittings are made from blackened copper.Tang peened over the butt.
Overall Length: 530 mm.
Thanks for watching.
