The power that can be invested in a tool can be astronomical, and to demonstrate this I'd like to highlight the Opening or Closing by Sceptre than can be employed by a hasty Hierophant. Z1 states:
"[The Sceptre] represents [the Hierophant] as touching thereby the Divine Light of Kether and attracting it through the Middle Pillar to Malkuth. It is called 'The Sceptre of Power' and invests him with the power of declaring the Temple Open or Closed in any Grade, if time be short, and this is done by saying: "By the power in me vested by this Sceptre, I declare this Temple duly opened (or closed)."
While it is true that this power comes from both the Hierophant and Kether, it still literally states the importance of the Sceptre itself. In fact, the power is vested in the Hierophant by and through the Sceptre, as a conduit for the energy from Kether. This potency is affirmed on a regular basis in the Equinox Ceremony, where the laying down or claiming of an implement symbolises the end or beginning of one's service as the respective Officer. These points alone should highlight the value of the employment of such tools in ceremonial practice.
