Editing Longship (section)

===Ship builders' toolkit===

At the height of Viking expansion into Dublin and [[Scandinavian York|Jorvik]] in 875–954&nbsp;AD, the longship reached a peak of development – for example, the Gokstad ship built in 890. Archaeological discoveries from this period at [[Coppergate]], in York, show the shipwright had a large range of sophisticated woodwork tools. As well as the heavy adze, broad axe, wooden mallets and wedges, the craftsman had steel tools such as anvils, files, snips, awls, augers, gouges, draw knife, knives, including folding knives, chisels and small {{convert|300|mm|in|abbr=in}} long bow saws with antler handles. Edged tools were kept sharp with sharpening stones from Norway. One of the most sophisticated tools was a {{convert|25|mm|in|abbr=in|0}} diameter twist drill bit, perfect for drilling holes for treenails. Simple mechanical pole wood lathes were used to make cups and bowls.
