Machining tool with deployable blade

A machining tool comprising:

• an elongated body forming a duct therewithin, the duct extending along an axial direction from an inlet at a first end of the body to a portion of the body at an opposite second end having a first lateral opening;
• a plunger configured to be movable between a first position closer to the first end of the body and a second position closer to the opposite second end along the duct;
• a resilient element for pressing the plunger toward the inlet to remain in the first position;
• a pivotally deployable blade deployable from the first lateral opening between a deployed state, when the plunger is held in the first position by the resilient element, and a retracted state, when the plunger is pushed towards the second position against the resilient element,
• wherein the deployed state of the deployable blade is a default state where no external forces are applied to the machining tool and the deployable blade is maintained deployed, except for when the plunger is moved to the second position, and when the deployable blade is pressed into the body, and
• wherein the deployable blade is connected to the plunger via a connecting rod that includes an offset that is pivotally connected to the deployable blade away from a pivot axis of the deployable blade.
