Mannlicher; Thanks for the interesting thread and thanks to all who've responded.
After years of carrying a succession of Spyderco's - Delica, Endura, Centofante III and then a Native - I bought a Buck Vantage Pro.
It's too early to tell if it will replace the Native or not as it doesn't fit the pocket quite as well. However, I will say it does open almost as slick as an assisted blade, is very easy to clean and the Bos treated S30V will take a fine edge.
As well an early Leatherman Wave always rides on my right hip as well.
