Abstract: The RAZOR TIP is a carpenter's pencil sharpening guide. It is designed to be used with a utility knife. Carpenter's pencils are traditionally flat, and wide in shape, making them difficult to sharpen by hand. The RAZOR TIP solves this problem. At the time of this patent application filing there was only one other similar type product available on the market. However, this pencil sharpener was only good for creating a round point on a carpenter's pencil. This defeats the purpose behind the design of the carpenter's pencil. It is designed to provide the user with a flat, and wide lead point which is less susceptible to damage when used on unfinished, and rough surfaces. The RAZOR TIP maintains the original shape of the lead point.
