just got back from the trip of a lifetime. went from Birmingham, Al up to South Dakota and Sturgis, Mt. Rushmore, Crazy Horse Memorial, Devil's Tower, Yellowstone then down to Utah and the Colorado river further down to Az. and then over to Colorado and then home via Texas. whew 5110 miles 10 days on my harley. well the reason this fits is that i took my 171UH for a knife, hatchet and semi safety. worked good in the first two getting firewood for camping (oh forgot to say camped out every night) and didn't need the last aspect fortunately. such a sturdy knife and still no wobble. it was a non-serialized version.
