An extremely useful tool to any artist, book binder, or paper crafter. The square shape easily fits in your hand, giving you more leverage to maneuver and use the broad knife side of the tool. The 45 degree edge allows for a natural fit in your hand. This can then be used in many ways, including squeezing bubbles out to ensure good adhesion when gluing two flat surfaces together. For instance, during the book binding process when gluing leather to the outside cover. Size: approximately 2" x 3" x 1/4" (hand made). Non-stick, will not leave a burnishing mark! Heat Resistant up to 600 º F. Chemically Inert, non-corrosive, and non-contaminating. Strong and reusable- teflon folders last for a very long time!
