<p>A safe knife is provided by utilizing a spring operated blade guard which automatically covers the blade of the knife at such times when the knife is not in use. The blade guard includes a knife guide plate which serves to correctly position the knife blade for a cutting operation, and the blade guard is retractable into an outer shell or handle of the knife against the compression force of a spring when a cutting operation is undertaken by a user, so as to expose only so much of the blade as required to efficiently perform the cutting operation.</p> |
