Abstract: A strawberry corer/stemmer tool comprises a tubular portion and a handle. The tubular portion has a partial bore connecting an insertion end of the tubular portion to a rear opening. The bore is slightly smaller than the transverse dimensions of a stem end of a core of a strawberry such that the core is urged from the strawberry. The core being removed from a subsequent strawberry forces the core removed from a preceding strawberry through the bore, with the result that removed cores are ejected through the rear opening. The wall edge of the insertion end is blunted such that strawberry leaves remaining attached to the previously removed core are similarly urged into the bore and are subsequently ejected with the previously removed core attached thereto.

Abstract: 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.
