Two-handed excavator for demining
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 is made entirely of malleable
steel with reinforced welds between the handles and the angled shaft to prevent separation in a blast. The
long shaft makes it difficult for a deminer on his/her knees to dig vertically. 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.
The user’s forward hand
is protected by a pliant and washable ballistic aramid hand-guard.
A pit to the required depth is made well in advance of the detector-indication. The deminer then works forward with smaller tools.
