An assisted opening multitool comprising:
- a first handle having a longitudinal axis and a lateral axis, the first handle having first and second longitudinal regions, the first handle having an interior surface defining a channel region,
- a second handle having an interior surface defining a channel region,
- a tool member pivotally attached to the first handle and operatively configured to be positioned in a closed orientation within the channel region and configured to rotate in an opening direction to an open orientation,
- an assisted opening system comprising a spring system operatively attached to the tool member where the spring system provides rotational resistance of the tool member for a first portion of rotation of the tool member from the closed orientation to the open orientation, and the spring system provides positive torque for a second portion of rotation between the closed orientation and the open orientation where the second portion of rotation is after the first portion of rotation from the closed orientation to the open orientation of the tool member with respect to the first handle.
