Interesting facts and notes
Much of the Lexicon's historical information on the development of brooms comes from this chapter.
...the invention of the Cushioning Charm by Elliot Smethwyck in 1820 went a long way towards making broomsticks more comfortable than ever before...
This was also discussed in an earlier chapter.
...nineteenth-century broomsticks were generally incapable of achieving high speeds and were often difficult to control at high altitudes.
For some value of "high".
...the Oakshaft is a handsome broom with a very thick oaken handle, designed for endurance flying and to withstand high winds.
Too cumbersome to turn at high speed, the Oakshaft...
This may be due partly to the wood from which the broom is made, and/or to the thickness of the handle.
Apparition becomes increasingly unreliable over very long distances, and only highly skilled wizards are wise to attempt it across continents.
The Moontrimmer...these slender, ash-handled brooms
The Moontrimmer's principal advantage over other brooms was its ability to achieve greater heights than ever before (and remain controllable at such altitudes).
The Firebolt's handle is also made of ash.
....the Twigger has been found to warp under high speeds and has gained the unlucky reputation of being flown by wizards with more Galleons than sense.
(Before that time, wizards preferred to take ships rather than trust broomsticks over such distances. Apparition becomes increasingly unreliable over very long distances, and only highly skilled wizards are wise to attempt it across continents.)
The patented Horton-Keitch braking charm meant that Quidditch players were much less likely to overshoot goals or fly offside, and the Comet now became the broom of preference for many British and Irish teams in consequence.
However, though highly finished and including a number of new gimmicks such as an inbuilt Warning Whistle and Self-Straightening Brush, the Twigger has been found to warp under high speeds and has gained the unlucky reputation of being flown by wizards with more Galleons than sense.
