A knot can be "reversed" by tying it with the standing and working ends reversed. The result must be topologically equivalent to the unreversed knot.
An easy example of this is the §bowline - when completed, the §sheet bend structure is obvious, but the way it is tied is reversed.
In contrast, the §lapp knot may appear to be a "reversed" §sheet bend, but topologically they are not equivalent as the working end comes out of a different part of the knot.
