The tools separate into roughly three areas: embossing, perforating and edging.
Embossing tools whiten the parchment. They are usually either a ball shape or a shader which has a loop shaped like a spoon. They come in various sizes from a large size (mega ball or mega shader ) to a small size (micro ball or micro shader) embossing tools are also used for stencilling. A scriber has a sharpish point and is used for lines and stippling. Sun tools emboss a circle shape like a small flower.
Perforating tools pierce the parchment in various patterns. PCA make two types: fine tools and bold tools. A single needle tool, however, will create all the patterns but it may take more time.
Edging tools pierce the parchment in a scallop pattern or v pattern. The stamp edge creates a perforation that will tear easily. A neater finish can be obtained by using parchment scissors.
