As the summary put it so plainly, knives need to be made with sheaths that can retract into the handle. These knives would appear to be just long, multi-layered boxes. However, push a button on the side and the cover on the blade retracts somehow into the handle, leaving it free for use. The button could
even have a safety latch of some sort to keep children from being able to use it. Also, the top end could be covered with some sort of flexible foarm or rubber with a tiny slit in the middle for the blade to slip through. This way there is no hole at the top to stick fingers in and get cut. This is safer then switchblades because the blade is not extending out of something; it is simply being revealed. The push of the button does not lengthen the possible weapon but opens it up for use.
It would be useful mostly as a safety measure for children who can pull most kitchen knives easily out of their sheaths if they can get to them. With a retracto-sheath, you can even hand a covered knife to your child, tell him to run it over to daddy, and have no fear of him tripping and cutting himself (not that we should encourage children to run with knives even if they are sheathed).

Fine if the handle is as long as the blade. My kitchen knives (a Rostfrei set of 21) has only two where this is the case. |

I think [smizzou] is talking
about a segmented sheath that
would progressively collapse
into the handle. |
|
| |
I like the idea. Make the
sheath spring loaded so it can
be deployed via a button (which
has to be pressed to retract
the sheath) on the handle and
I'm sold. |

And the sheath only needs to cover the sharp edge[s] of the blade, so wouldn't take up much volume; perhaps it could be wound into the handle of a long knife. |

For a real safety latch, give it a proximity sensor to something you stick on the wall at the shortest adult's highest arm-reach. Not only does this button the blades against nimble-fingered, imitative children, but it adds drama to the evening's cooking. |

Each household could develop its own view-halloo as the cooks brandish their cutlery in the air; 'There can only be won tons!' 'Prrrrresent Armpits!' etc etc. |

Guest souschefs would be a problem, UnaBubba - how about an iButton ring? Could be handed out with the knife but would have the safe-drop feature. |
