DRE,
The very first gen WWII KA-BARs were more oval than the others (and they were hand finished) but eventually the later generations became more round as handle profiling machinery was built to handle the large volumes. The leathers on the first gen knives were thin on the top as more leather was removed on the top as opposed to the bottom. As you can imagine that wasn't a good idea in the jungles of the Pacific.
If you have a chance to handle the Camillus, Ontario and early KA-BAR versions: Camillus was the fattest of the round handles, Ontario is thinner, Old KA-BARs varied from both fat and thin. Probably depended on who was running the profiler.
The government spec is fractional when it comes to the handle dimensions so there is some lenience built in.
The Small KA-BAR F/U has the handle in line with the centerline of the blade. We did away with the offset for that model.
Hope all of this helps. I don't mean to hijack a KA-BAR thread as I don't work there any more, but I consider all of you as knife friends and hope you don't mind.
Best Regards,
Toooj
