Just bought this. It was on sale and I had a $60 coupon about to expire so total net cost was $67. They come from right down the road from me so I can drive over and get free lifetime sharpening. Obviously a no brainer purchase.
I like it. The handle has a sort of suede texture. It's slightly less long, which is noticeable when opening one handed. The size is less noticeable in the pocket though. It can be opened one handed but isn't as fast to pop open as the Spyderco, which is fun to flick open. But this mini Osborne is easier to close one handed than the Spyderco, which I have to be more conscious of keeping my fingers out of the way. Closing the Osborne seems more ergo, that is a natural feeling. It also feels more "refined" snapping shut. Like it's softer and more controlled. It is even quieter closing. The Spyderco has a satisfying metallic click when it snaps shut. Not that one is better than the other but they are different.
The shorter handle of the Osborne is compensated by a knurled thumb grip near the hinge. The finger opposed to the thumb gives a solid control, but it doesn't fit as perfectly as the longer handled Spyderco. It's a compromise for the fit in the pocket, but that really doesn't feel like that much to give up. Side by side, it's surprising how much smaller it appears, as it doesn't feel that much smaller in the hand.
Not sure what to say about the blades, as this is more technical than my knowledge. The Osborne blade appears beefier, maybe even more refined. I think it's likely deceptive as my Spyderco is a flat blade with no bevels. There's more texture on the Osborne. I have no idea which will hold an edge better or what the real differences are besides appearance.
It's a nice looking and feeling knife. The darker green is very attractive and I like the little purple accents.
