Strauch Teasing Tool
You might call this a single flat hand card, but you use it in a different way. Clamp the tool near your drum carder or even near where you are hand carding and pull your wool over the teeth to open ends and begin the process of cleaning and carding. Both hands are free to do this since the tool is clamped. Makes for faster, more efficient carding. 5.5" x 4.5". 112 Teeth per square inch. Comes with a C-clamp.
