The early medieval smiths achieved heights of craft skill not matched until the industrial
revolution. They exploited the full range of iron alloys and produced exceptionally
high quality steel, which were utilised in their edged tools, particularly knives.
Another exceptional craft skill is pattern-welding, the deliberate manipulation
of alloys to create a decorative pattern.
