I am not sure about the new ones from the Kabar company, I have not used them. The old ones were made by Camillus and had a very narrow tang. Mine broke at the hilt. I had a bit of bending as well. These experiences were indeed during military training or operations. I began a quest to find the indestructible knife. The ones I found then (1980s) were a Gerber BMF and a Cold Steel Recon Tanto. The Tanto was not a good design for field work, but it was very tough. I actually tried to break these knives and put them through hell. Other than some nicks and wear, they held up to serious abuse.
The knife industry is very different now. In the 1980s, if you wanted something really good, you bought a Randall. I could not afford that. Now there are many choices, and more demand for quality, at least in the social environment I am in. There is a greater understanding of what to look for in a knife, at least for me.
When you are out for a long time, don't have many choices, can't get additional tools when the mission changes, you carry one good one that will not break, no matter what you do with it.
