Razertip makes several different styles of woodburning pens and each has its own unique ability. We have found that with all the different shapes there are really 3 different types of wood burning pens to choose from to cover the majority of woodburning textures; a Writing Pen, Skew, and Shader. We recommend to start with at least one of each style when you get started. This way you will have a burning pen for thin lines, curved lines and writing, and for shading larger areas. If you are looking for very specific textures for making fish scales, circles, or even making your own tips check out the Misc Woodburning Pens.
