Essentially, we carried these contenders for day-to-day use. Like "real-life" usage, our testing included a variety of tasks. We used every knife for tasks like cutting apples and cheese and opening packages. Incidentally, note that cutting cardboard is one of the more abrasive routine tasks one can ask of a knife. Cardboard, while appearing soft and innocuous, usually includes a great deal of impurities picked up during it's construction (dirt from the logging process, metal filings from machinery, etc). This is the primary reason that those working in environments where cutting cardboard is a daily task use "box cutters" with disposable blades. To purposely test these models knives in more demanding tasks we cut rope and webbing with each one. We also carved and whittled wood, testing well beyond the manufacturer's intended purposes by boring holes with the tips of the blades. The tools with more than just a blade (Victorinox Classic, SOG Trident Elite Assisted Opening, Neokut Black Kryptonite) were tested in their diverse applications as well. In the interest of full disclosure, however, we did not bash through glass with the tactical knives. We'll take their word for it. Finally, it is worth noting that the lead tester owned the Victorinox knife as a kid. He received the Classic model at a very young age and used it for a number of years. Like young kids will, he abandoned the Classic until this test.
