In army we were issued a camillus TL-29. The internet wasnt much back then (2000), and no one used it like we do today, so the idea of looking up a brand name wasn't one we thought of. So everyone wondered what this knife was designed for, what the locking screwdriver blade was for (seeing as we didnt have a whole lot of screws in our issue gear) and why it was sharpened half way down. Everyone hated the fact the main blade didn't have a liner lock, because slip joints were no good for some rougher army tasks. Lots of people opted for a brand they knew like Victorinox and leatherman, while others found the TL-29 too heavy, so they got left behind after basic training ended. No one carried a tactical knife or large fixed blade, because they served no useful purpose and added weight.
In my police career I was issued a leatherman wave, which I carried on overseas ops, but wished I had a larger knife! I didn't carry a gun so the leatherman was all I had for self defence. It wasnt much when the locals all carried machetes, and guns, and sometimes used them to attack our officers on patrol. Probably the only time a bigger knife like a bk tweener would have been of any value.
