Thanks for your input KenK!

You involuntarily touched a sore spot by mentioning the Ritter Rsk knives. I've been meaning to purchase one or two for years, especially the Rsk 1 Mini, and now that I've made up my mind, they're gone out of production and the Ritter Rsk 1 is on sale for exorbitant prices on Ebay...

The Rsk 2 is indeed a little too big for me, not only for practical reasons but also for social ones. The area where I intend to use the knife is fairly settled and I don't want to raise too many eyebrows by toting around a big blade.
For the same reason I would avoid any "tactical" looking knife.
