Abstract: A deflectable safety shield extends transversely across a cutting plane in a protective guard position completely overlying the cutting edge of a utility knife. A portion of the shield extends over-center with respect to the cutting edge, thereby tending to hold the shield in the guard position in response to contact of the shield against the operator at the normal angle of engagement during follow-through that accompanies rapid slicing hand movements. The shield is resiliently biased for movement to the guard position by a torsion spring. An outwardly-turned flange portion of the shield provides an angularly offset leverage point for reacting the torsion spring when the operator desires to perform a cutting operation. The shield swings away from the cutting plane automatically in response to pressure engagement of the offset flange portion against the box surface, thus exposing the cutting edge.

Abstract: A manually operated floor grooving tool is provided which has opposing front and rear ends with a seam-following roller at its front end and a groove-following roller at its rear end.

Abstract: An air deflection system and method which is specifically designed for use with reciprocating saws of the type widely used for construction projects. Such reciprocating saws are known to produce so much air-borne particulate matter that they can be a hazard to the eyes, head and respiratory system of the user. The air-borne debris also makes it difficult for the user to see the work being cut. The design provides a slip-on cover for air exit ports which has the effect of deflecting air and hence the particulate matter in a direction away from the head of the user. The resulting effect is a safer and more efficient sawing operation which is accomplished with a low-cost and easy to install deflection shield.

Prior to the initial use of the guide plate, it is trimmed to size by a power saw guided by the rib member so as to specifically tailor the guide plate to the power saw with which was used to make the initial cut.

Abstract: The present invention encapsulates a razor blade in a relatively thick and durable plastic. In the plastic there are provided a number of comb-like projections which extend beyond the blade edge while still leaving the edge exposed between the protrusions. These protrusions serve to guard the blade from accidental contact, thereby enabling the present invention to be safely carried, even in a person's trouser pocket. Other features are molded into the plastic at the time of manufacture which allow the invention to be hooked onto a key ring and which further enable line of indeterminate length to be wrapped longitudinally about the invention. Due to low cost of manufacture, the present invention may be disposed of when the blade dulls. The plastic serves as a protective guard even after disposal, offering environmental resistance comparable to that of the blade.
