A system and method for enabling highly scalable multi-node event distribution networks through the use of summary-based routing, particularly event distribution networks using a content-based publish / subscribe model to distribute information. By allowing event routers to use imprecise summaries of the subscriptions hosted by matcher nodes, an event router can eliminate itself as a bottleneck thus improving overall event distribution network throughput even though the use of imprecise summaries results in some false positive event traffic. False positive event traffic is reduced by using a filter set partitioning that provides for good subscription set locality at each matcher node, while at the same time avoiding overloading any one matcher node. Good subscription set locality is maintained by routing new subscriptions to a matcher node with a subscription summary that best covers the new subscription. Where event space partitioning is desirable, an over-partitioning scheme is described that enables load balancing without repartitioning.

In accordance with this invention, an underside or lower scissors handle, which is conventionally attached to the upper blade of a pair of scissors, is provided with a separate, appropriately sized, additional hole or loop-like band for receiving the index finger of the user. This additional index finger hole is located forward of the main lower finger opening. This unique placement of a separate index finger hole, which is a primary feature of this invention, isolates the index finger against the shaft of the scissors and closer to the pivot point of the blades, and allows the index finger to guide advancing motion of the scissor blades to the right or left as needed to follow a desired path or pattern, for example forming or following a curve. A separate third hole for placement of the index finger makes these scissors unique. Isolating the index finger against the shaft of the scissor handle provides stability and strength and allows the index finger to adjust or “guide” the scissors to the left or right making easy and very subtle adjustments as needed to negotiate curves and angles as in following a pattern. Another feature relates to the “thumb hole” in the upper handle. The inner diameter of such upper handle thumb hole is limited with a suitable restraint, such that the thumb enters only by an amount sufficient to keep the thumb in flexion, and not far enough to place the thumb in extension.
