I have a Classic Sebenza that I would not call NIB only because I traded for it and cannot vouch for any previous use. It looks to me to be new but there is a very slight scuff on the pocket clip. Other than that I cannot see anything that would indicate it has been carried or used. The lanyard is tied and it has all the papers and packaging. I am not sure what you mean when you say that you do not like the thumb grooves, but if you are referring to the grooves on the spine of the blade, this one has the original smaller grooves.
Thank you,
Dale Richmond
