A spiral is the begining and ending of everything. Nature tends to grow many of her plants with a spiral. It is strength in form with finesse.
Electricity moves through copper wire in a spiral fashon, as it moves forward it turns clockwise, magnets work in the same fashon. The planet spins in this same clockwise-forward direction. Our amulets are designed on this concept. This type of spiral within a magic wand will aid in the flow of energy, collecting energy and moving it through the spiral creating a vortex of energy within the wand.
There is another form of spiral, one that twists in the opposite direction. This spiral is one of banishing or removing energy.
This type of spiral creates a vortex that pulls in energy rather than collecting and emmiting energy. Although this would work well for cleansing, banishing and removing excess energy, this type of spiral within a wand could also remove wanted energy. This is why Merlin's Realm has not made any full negative spiral wands. If one would be constructed it would be more functional with a positive spiral handle and a negative spiral shaft and tip.
All of our Wands are made with a positive spiral design.
