Here is a Carrier Intrenching NSN8465-21-893-2151 made by Manta Industries in 10/83, which is a variant designed to carry the older e-tool as used in the P51 and P64 websets. It is not shown in the Pattern 82 guidebook, so I assume it was a stop-gap until the fancier e-tool and its carrier was ready for issue.
Here is the comparison with the P64 carrier version
I have also include a photo of the venerable 1953 E-tool with integral pick, which was a pretty functional inplement in the Petawawa sand at least.
Question for the group: is the P82 e-tool still in use or is it consigned to stores as unusable? I never see any photos with troops hauling them around.
