demining hand tool was first designed by MIT to meet the rules required to ensure that a tool does not separate or fragment in an anti-personnel mine blast. The tool is intended to replace the pick-axe (still widely used) when starting an excavation on ground that is very hard.
MIT did not make or finalise the design, so I did.
The excavator must be made entirely of malleable
steel, E304 stainless steel whenever possible. There must be reinforced welds between the handles and the angled shaft to prevent separation in a blast.The angled shaft has a sharp tip and is easy to direct accurately when starting an excavation.
The two-handed digging action copies the two-handed 'hammers' used by the police to force open doors, maximising the user's force while minimising effort.
