Yeah,it has been asked and answered before. But since I never mind sharing my arrogant opinions, here goes.
I own and carry both a Sage 2 and a small micarta 21. The Sebenza is everything that is good about a well made, hand fitted, small folder. The materials and workmanship are outstanding and that is true from one Sebbie to another (I've had about 15 by now of all sizes and styles).
I've had two Sage 2s. I sold the first one, immediately regretted it, and latched onto another one. The thing I noticed about the two Sages that I personally held and used is that they were exact clones of each other. They both locked up in exactly the same place and the lockup never moved during the months that I had them. They were both fantastically sharp with very even bevels. They both had very smooth opening/closing action.
My opinion (and that's all it is) about the two knives is this. I'm really glad to own my Sebbies. I use the micarta 21 quite a bit and I have two dog paw Sebbies with all my dogs' ID disks on the lanyards that will go into my coffin with me (as a reminder of my dogs, not just because I like the knives). My wife's EDC for several years has been a small dog paw Sebbie and it's still going strong even with no return visit to the "spa" for a tune up. The micarta 21 is a bit more comfortable for pocket carry and EDC cutting tasks.
It really feels good in my hand as long as I'm doing short and light cutting tasks.
The Sage 2 is my choice for heavier duty or longer term cutting with one of these two blades. I've found the wider Spyderco blade and the continuous curve to be very useful around the house, garden, and woods where I live. And I already knew that I liked Spyderco's curved edge shape for warehouse work. Spyderco's edges are the easiest for me to maintain of any brands that I've ever owned. They last a long time and they come right back with a Sharpmaker faster than any blade I've tried to sharpen. The materials and workmanship in my Sage 2s have been equal to any of the Sebenzas that I've had and I have a preference for Spyderco's edge bevels and their factory sharpening standards that I've stated many times before.
For me and me alone, The Spyderco is superior in function to the small Sebenza and is it's equal in materials and workmanship, making it a better dollar value to me. I do not think that the Sage 2 is a "Sebenza-killer" as was suggested early on in it's development and production. For a knife knut, a Sebenza is in a class by itself.
But then... so's Spyderco
