DIY Knifemaker's Info Center: Knife Patterns
Both plywood and polycarbonate are easy to shape with sanders and files until they represent a perfected shape. Once made, I can make many copies on to steel. A busy knife maker will make patterns out of steel, where 100s of knives can be made from the initial pattern. So it's about durability. Cheers, Dan July 7, 2014 at 9:52 PM
