Abstract: A stackable stamp assembly used to form images on a surface includes a substantially congruent and releasably engageable base, intermediate members, and cover assembly. A stamp is attached to each of the intermediate members. The intermediate members are dish-shaped so that the stamp of an upper member is received within the member disposed immediately below when the members are stacked one on top of the other. The assembly may also includes ways to facilitate the alignment of the assembly with the surface on which an imprint of the stamp is to be made.

Abstract: A pivoted hand tool, such as a scissors, includes a pair of blades having non-rectilinear cutting edges to form various cutting patterns on a sheet of paper. The scissors also include at least one guide to control the angular presentation of the paper to the blades and limit the amount of paper presented to the blades. The guide may also include a pair of ridges spaced apart from a pair of abutting surfaces, thereby providing a way to further limit the amount of paper presented to the blades. The scissors preferably have identically-shaped handles and oppositely facing guides to enable a user to create several complementary patterns on the sheet of paper simply by reversing the position in which the scissors are held.

Abstract: A paper trimmer includes a base and a plate pivotally attached to the base. A carrier is slidably attached to the plate in an elongated slot. A blade assembly includes a blade secured to a blade holder. The blade assembly is received in a cavity formed in the carrier such that a cutting edge of the blade extends below the plate and is received within a channel formed in a cutting region of the base when the plate is disposed over the cutting region. A paper is cut by translation of the carrier along the slot of the plate.
