I think a pattern is a commonly produced design. Before machinery and mass production, cutlers had patterns or templates for the different knives they produced. They often stored these in tins. The templates were heavy steel so durable. They would use these templates as a guide to cut the liners, shape the blades, drill the holes, shape the springs etc. There were steel templates for drilling the recesses in the handles for the shields and so on. Literally it was a patten for constructing a particular design of knife.
