Iron Imperative
Chisel needs no hammering or external force. 
Inspiration from Nature
Odontodactylus can strike with a lightening speed in water by using the energy released from an air bubble that gets burst.

Problem Statement
Different types of chisels are used in carving and sculpting of materials like stone, marble and wood etc. There are two important aspects of chiseling, pointing of the tip and the force with which it is hammered. Chiseling can quickly become a tedious task and demands steady hands. This, gives advantage to men over women which is wrong because sculpting is an art form and art is gender-less. Chiseling needs to be liberated from hammering altogether.
Nature Review
Skeletal system with conventional energy input-output principles fail to generate the kind of force required. We need a new model to generate maximum impact with minimum force. A mantis shrimp (Odontodactylus) already produces such tremendous force through the process of power amplification called ‘Cavitation’. In this process the force emitted from the busting of air bubbles in water is used for propulsion. It paves way for a water-based chiseler in which air bubbles are created and burst for power amplification.
Technology Review
The process of Cavitation is used in propellers of a boat however, in-depth analysis of the deadly strike of a mantis shrimp reveals that more than one systems need to be amalgamated in the designing of a zero-input chiseler. A few good study cases are Bosch Demolition Hammer, Arbortech Power Chisels and Foredom Chisel Hand Piece (presented below). The Nature Gadget should be battery-less device, ready to be used anytime.

Nature Gadget
A chisel has liquid compartment (13) where air bubbles are formed and burst continuously to release energy in process called Cavitation (22).  Metal tip of the chisel can strike either rapidly or just once (12). And impact of the recoil gets nullified before it reaches the hand, like in ballet slippers.
