Kirby metal wands, horsehair brushes???
Yeah right!
I can clearly imagine people griping about the weight and inconvenience of metal wands and accessories!!! The complaints about the weight of the Kirby would only intensify and I believe sales would diminish. Also, can you image what it would do to the cost if all attachments were metal and brushes sourced from horses??? YIKES!
I think Kirby accessories are great as is. I think they "look" just swell, and they perform even better if you twist and lock them as intended.
Also, keep in mind Kirby Company does not set the selling price of their own units. That is done by the Independent Distributors.
