A book holder including an elongated, flexible formed piece of material, the material having an elastic deformation characteristic so as to permit bending while remaining biased to an original position, a base formed from the material, the base having a first member substantially transverse to a second member and a third member substantially transverse to the second member, the first, second, and third members lying in a plane, a first arm, having a first and second portion and a tip, formed from the material, the first portion extending from the first member generally perpendicular to the plane and the second portion extending obliquely from the first portion, the tip being on an end of the second portion opposite the first portion, a second arm, having a first and second portion and a tip, formed from the material, the first portion extending from the first member generally perpendicular to the plane and the second portion extending obliquely from the first portion, the tip being on an end of the second portion opposite the first portion wherein when the material surrounds the book in an open position, the base contacts a cover of the book and the tip of the first arm and the tip of the second arm each contact a page of the book, and when the book is in a closed position, the base contacts a first side of the cover, the first portion of the first arm and the first portion of the second arm contact a middle of the cover, and the tip of the first arm and the tip of the second arm contact a second side of the cover.

A method of placing an object having a substantially planar surface into a channel between a pair of teeth, implemented by a grasping tool, including providing a dental tool having a first arm with a first tip and a first end, a first pressure portion on a first surface, and a pin mounted on a second surface opposite the first surface and a second arm with a second tip and a second end, a second pressure portion on a first surface and an opening that receives the pin, applying pressure on the first pressure portion and the second pressure portion simultaneously to grasp the object, moving the dental tool and the object toward the channel, inserting the object into the channel, and releasing the pressure from the first pressure portion and the second pressure portion to free the object from the dental tool; the first end affixed to the second end to form a base, the first tip and the second tip substantially oblique to a plane passing through the base, and the first surface of the first arm opposite the first surface of the second arm. The grasping tool including a first arm having an angled first tip, a first end opposite the angled first tip, a first surface, and a second surface opposite the first surface, a second arm having an angled second tip, a second end opposite the angled second tip, a first surface, and a second surface opposite the first surface, where the second end is affixed to the first end to form a base, the second surface of the first arm faces the second surface of the second arm, a plane passing through the base between the first arm and the second arm, a pin mounted on the second surface of the first arm, an opening through the second arm that receives the pin, a first pressure portion on the first surface of the first arm, a second pressure portion on the first surface of the second arm, a first mating portion on the second surface of the first arm and opposite the first pressure portion, and a second mating portion on the second surface of the second arm and opposite the second pressure portion; the first angled tip and the angled second tip substantially oblique to the plane passing through the base while the tool is in a closed position, a portion of the angled first tip and a portion of the angled second tip mating when the tool is in a closed position such that the pin engages the opening, and the second mating portion contiguous with the first mating portion when a maximum pressure is applied to the first pressure portion and the second pressure portion.
