The 2010 iteration of Kershaw's Oso Sweet, model 1830 is different. Is different good? Some changes are for the better, like the 8Cr13Mov stainless steel blade; better by most accountsbetter than the former AUS6a. Some changes are fine, like the visible stainless steel liners which were formally hidden, wrapped around by the FRN handle material, also the fact that the blade is now hollow ground, instead of flat ground; a plus in some peoples books. Some changes are not so sweet, like the new grind area; I don't like it! I loved the way the previous version was ground. That high, thin, flat steel area that pushed out a wide swath of flat-ground gorgeousness is gone, replaced by a pretty average looking blade grind. Other changes, at least on this sample, are bad! I'm dealing with a specimen that I believe has a manufacturing defect. The blade makes contact with, and puts pressure against the right side liner to a degree that the deployment is slowed down. Also, as demonstrated in the video, the blade exerts that sideways pressure early on in the closure of the blade, and can be made to easily stop in a semi-opened position that this spring assisted opener should not be able to do. I'll work with Kershaw to address this defect, and hopefully get a new knife soon. Until then, take a closer look at your 2010 Kershaw Oso Sweet, and let me know... is it still so sweet? ... https://www.youtube.com/watch?v=xes9BbVxb_s
