It seems that such tools as Rose's wands and Dave's timetables serve more as a focus for their abilities then anything, however the way Rose casted (or rather the voidy effects) when she used Horrorterror-infused wands and the implication that anyone can use timetables if they know how imply that a tool can also be "aspect infused" on itself. So using tools is preferable but only nessesary when you need effect out of your league or when you are in process of getting accustomed to flashy powers.

Sounds like a fair assessment, and also makes you wonder what household items may infuse your weapon with Aspect Majyyks just because they’re tangentially related.
