Points to Consider
- The following image is of a sword constructed of an alloy known as Damascus steel.
Notice the mottling pattern, reminiscent of flowing water. Damascus steel blades were a product of medieval times
and were highly regarded for their toughness, resistance to shattering, and their capability to be honed and sharpened
with a resilient edge. Even to this day, it is still debated as to exactly how Damascus steel was made.
