Elm, 10 3/4”, Unicorn hair, Unyielding
I’ve been on Pottermore for a while now, but I just want to share my wand again, and the descriptions of the components, because I love it so much.
The unfounded belief that only pure-bloods can produce magic from elm wands was undoubtedly started by some elm wand owner seeking to prove his own blood credentials, for I have known perfect matches of elm wands who are Muggle-borns. The truth is that elm wands prefer owners with presence, magical dexterity and a certain native dignity. Of all wand woods, elm, in my experience, produces the fewest accidents, the least foolish errors, and the most elegant charms and spells; these are sophisticated wands, capable of highly advanced magic in the right hands (which, again, makes it highly desirable to those who espouse the pure-blood philosophy).
Unicorn hair generally produces the most consistent magic, and is least subject to fluctuations and blockages. Wands with unicorn cores are generally the most difficult to turn to the Dark Arts. They are the most faithful of all wands, and usually remain strongly attached to their first owner, irrespective of whether he or she was an accomplished witch or wizard.
Minor disadvantages of unicorn hair are that they do not make the most powerful wands (although the wand wood may compensate) and that they are prone to melancholy if seriously mishandled, meaning that the hair may ‘die’ and need replacing.
Wand length and flexibility
Most wands will be in the range of between nine and fourteen inches. While I have sold extremely short wands (eight inches and under) and very long wands (over fifteen inches), these are exceptionally rare. In the latter case, a physical peculiarity demanded the excessive wand length. However, abnormally short wands usually select those in whose character something is lacking, rather than because they are physically undersized (many small witches and wizards are chosen by longer wands).
Wand flexibility or rigidity denotes the degree of adaptability and willingness to change possessed by the wand-and-owner pair - although, again, this factor ought not to be considered separately from the wand wood, core and length, nor of the owner’s life experience and style of magic, all of which will combine to make the wand in question unique.
