This is just my opinion and it might be completely wrong, but the way I see it, the old Bucklites seem to be the predecessor to many of today's more popular lightweight knives. Put a spyderco delica/endura beside an old Bucklite 422/426 and also add in the mini and large griptilians and you can see many of the similiarities. The spydercos and benchmades just seem like a more modern advancement of the old original Bucklite design. That is about my only gripe with Buck knives. Seems like they came up with something really good with the lites and just stopped with it, unless they turned more into the bucklite max or bantam, which are good knives but it just seems like Benchmade and Spyderco really went with the lightweight concept and took it to the next level with g10, and different steels with a standard pocket clip and screw together where you can adjust out any slop..................
But again, I think I'll be tickled with any Bucklite whether it is the old original or upgraded. The originals were really ahead of their time if you think about it. Kind of a hunting knife/ tactical all rolled into one. When I was about 14, the old green Bucklite got you approval at deer camp from the old timers in camp that carried a 110 and it was the envy of most of my buddies whose moms wouldn't let them have anything other than a slipjoint. Not bad for a knife that probably cost $10.
