True Combat Value of Wootz

ariel,

I ask if you would be surprised if a chisel would cut through the said chain/armour. I think that the safe answer is no. Then why not?

Because a chisel's edge has a different geometry, more obtuse, AND because several hammer blows can impart the required energy - One just keeps on hammering until the cut is effected.

Of course, such edge geometry, except on a very specialized sword, would not do at all for an all purpose weapon. And then a single cut is unlikely to have sufficient energy to finish the job.

I have a utility knife that I made from a high speed alloy tools steel blade. Hard as hell and full of carbides (can barely sharpen it) . When a saw, it used to cut steel bars. Once, for an experiment I tried to cut a small, around 1mm dia, nail with it and the edge started to nick. Why? because its low angle edge could not support the load imposed on it. Cuts fine otherwise, but not nails. The steel is the same, but the edge geometry has changed.

GT Obach: A small comment on wrought iron chain

You are spot in your remarks. I just would like to add, that those slag inclusions in wrought iron chain are highly desirable because they act as crack arrestors. This and its superior corrosion resistance is why wrought iron is the preferred metal for ship's anchor chain - Very tough and shock absorbent, yet soft, malleable and easily hammer welded.

Cheers
Chris
