Listed a page back, NATO/NSN, date of contract/NOT date of manufacture, maker name/mark, and Ministry Of Defense "broad arrow" aka "crowsfoot" acceptance mark....for SURE any knife without these marks on blade or handle is a knockoff and probably Chinese....these come direct from Sheffield, black one is PN SHE004.

The front view of knife only needs a conning tower and front dive planes to make a dandy hunter/killer sub.

The actual measured thickness is approx. 0.245" in back, tapering to 0.240" up front, aside from primary edge grind areas. I have no idea if they started with 1/4" thick plate or 6.5 mm plate on these newer versions. Both would be slightly reduced by rough surface finishing and then built back up somewhat by parkerize.

PS- gotta maybe crawfish on assertion these newer knives not hotworked at all....at least, on THIS contract.....the blade does do above measured taper, and this blade does also gain in depth out front. It may have been hot forged/rolled to do that. Maybe even to point it needed the above post mentioned possible trim to spine to fit the issue sheath, trimming back edge not near as easy an option. (i love trying to figure out how and why somebody did something)

As for sharpness, the high flat grind has a less obtuse angle than any American issue fighting/utility/survival knife, and it has a thinner edge lacking any substantive secondary edge. Which means despite massive blade, it can be laid over further than such knives as the Jet Pilot/Marine Combat without the edge lifting up, and capable of finer angled cuts such as shaving bark or wood. It also means deeper bite in chopping, not even counting increased mass driving the edge. For a slab of soft steel, it is a good slab. The lower hardness also translates to easier field sharpening, and no chipping, much less, actual breaking. The hardness approximates that of the American JPK survival knife, but lacks the reduced tang of same and more like 1/4" thick rather than 3/16ths" thick....tough.
