I have the Strobe and just got the 3.5 inch Nura earlier this week and to me, the Nura feels cheap and flips something awful. Nothing at all like the Strobe and more closely inline with the skyline. The knife overall is think and does not feel sturdy at all but then again, it might be what they were going for. A slim styled knife. One thing that really urks me outside the flipping action is the lock itself. Mine came with it 100% engaged and has pretty sticky 'lock rock', which i have never had on any knife before. It also seems to bend when you disengage and use to much muscle, which makes me have to disassemble the knife to bend it back.
Overall i was very disappointed in the NURA and am very impressed with the Strobe. Given that they are the exact same price, I feel you are getting a lot more value for the money with the Strobe. Fantastic flipper, great fit and finish, and overall a great low budget flipper.
I don't see how anyone can compare the Nura to any of the fine flippers ZT makes, especially the 801 which is one of their best. Far closer to a skyline then anything else. At least that is how my knife came.
