I really liked Super Blue when I had my Caly 3.5. The patina looks really nice (love that bluish tint). It takes a REALLY sharp edge with very little effort. My big issue was the corrosion resistance. This steel will pit very easily if not cared for. Having moved from NY to TX, the humidity changed dramatically. I used Tuf Glide but I have a habit of using my EDC knives with food and I guess washing and drying the steel will cause Tuf Glide to dissipate quicker. Anyway, if you do not wash your knife regularly (since it isn't used for food) and are good about monitoring your knife and applying lube, then Super Blue is a really nice user steel.
If there was some way to make a Super Blue in stainless, I would jump all over it. It felt to me, and I am speaking with a lack of steel knowledge, like an upgraded VG10. Sharpened easily, cut cleanly and polished up very nice.
