A safety knife comprises a handle formed with an elongate narrow slot which extends transversely completely through the handle from one lateral surface thereof to the other, and extends lengthwise from a slot mouth in an outer surface of the handle to a location within the handle. The handle is formed in two halves which are clamped together by bolts, and sandwiched between the two halves is a blade having a cutting edge which extends at an acute angle across the width of the slot at a location spaced inwardly from its mouth. In use, string or similar material to be cut is passed along the slot until it meets the cutting edge of the blade, and continued pressure of the blade on the string then severs the string. Since the cutting edge is encased within the handle and is spaced from the mouth of the slot, there is little or no risk of the user being accidentally cut by the blade. |
