The Scratch Knife is a basic tool for scratching in details when using both Scratchbord, Claybord and Stampbord. This set contains two handles and each comes with two nibs, one fine point and one curved allowing for a variety of mark making techniques and experiments. The fine nib as the name suggests creates fine lines, whilst the curved nib creates wider more pronounced lines. Create different effects depending on the pressure and angle with which you use the knife and 2 blades.
