fig1 13 the u shaped guide can be configured so that when the cable fits into the guide the knife handle is perpendicular to the length of the cable alternatively the guide can be configured so that the knife handle is in oblique relationship to the length of the cable the embodiment shown in fig1 17 can be used to cut flexible flooring material such as linoleum or pvc sheets or tiles at the location at which the flooring material meets a vertical wall or baseboard handle parts 126 and 128 are secured together to form a knife handle 130 handle part 126 is formed as a unit with a guard part 132 and handle part 128 is similarly formed as a unit with guard part 134 when the handle part 126 and 128 are secured together by screw 136 guard parts 132 and 134 come together to form a boat shaped guide having substantially flat surfaces 140 and 142 which diverge from a knife blade 138 that protrudes through a slot 143 fig1 located where the surfaces 140 and 142 come together surfaces 140 and 142 are perpendicular to each other and each of them forms an angle of 135 u00b0 with the blade accordingly when the knife is used to cut flexible flooring sheets or tiles at the location at which the.
