There are many ways that raden is produced, with all techniques classed under three main categories: Atsugai (using thick shell pieces), Usugai (using much thinner pieces), and Kenma (the thinnest application of shell pieces). In Atsugai raden, the shell is often cut with a scroll saw, then finished with a file or rubstone before application. In Usugai raden, the thinner shell pieces are usually made using a template and a special punch. Kenma raden is fashioned similarly to Usugai raden.
