The most famous example of a multi-function knife is the Swiss Army knife, some versions of which number dozens of functions and are really more of a folding multi-tool, incorporating a blade or two, than a penknife with extras.
The sabre or saber is a kind of backsword that usually but not always has a curved, single-edged blade and a rather large hand guard, covering the knuckles of the hand as well as the thumb and forefinger.
The shovel fell from my hand across the box, and as I pulled it away the flange of the blade caught the edge of the lid which fell over again, and hid the horrid thing from my sight.
We all looked on with horrified amazement as we saw, when he stood back, the woman, with a corporeal body as real at that moment as our own, pass through the interstice where scarce a knife blade could have gone.
When ice skates are sharpened the blade is ground with a stone with a curved surface, dressed to either restore the hollow or provide a different radius.
