You might wish to try the BM 770 Axis Gent Folder, designed by Warren Osborne. It is one very dressy little knife with a 2.80" blade of 154CM steel with a drop point and a 3.75" hilt of carcon fiber that has been very nicely finished. The Axis Lock buttons, the pivot screw, the opening assist studs, and the near full length back spacer are all given very nice file work that adds the finishing touch to a nicely done gentleman's pocket knife. I note that there are now versions with black and gray anodized aluminum hilts for rather less money than the carbon fiber hilted versions. Despite its svelt appearance, this knife woks like a regular duty knife. It is easy for my arthritic hands to hold and to open or to close.
I am also very, very fond of the Spyderco Li'l Temperance, with its 3" blade of CPM440V steel, my favorite, in a very substantial G-10 hilt that is 4 1/2" long and very wide, giving you a goodly handful to control it. You reall have to feel this knife to believ how well it handles and how good it feels. This knife uses Spyderco's great Compression Lock, but reversed from the version on the Gunting, making it very much easier for me to close.
The Salsa is almost as good, but the blade is 2 7/16", making it legal in a Federal building accoding to 18USC930, and is made of AUS-8
steel, very much a lesser steel than CPM440V, IMHO, but it also makes the knife cost about 1/2 of what the Li'l Temperance costs at most online dealers, at least for the aluminum hilted versions. The hilts come in titanium or anodized aluminum, the titanium costing about 50% more than the aluminum and coming in gray only, while the aluminum comes in blue, green, or gray. I have the blue aluminum version and it works very well for my arthritic hands, as do all of the Spydercos that I am listing. This knife also uses the Compression Lock and it also has the "Cobra Hood" over the Spydie Hole to assist in opening the blade, With its machined grooving on the top, it also provides a nice purchase for your thumb when you need to apply a bit of extra pressure or control to your blade.
You might also look at the Meerkat as someone else has suggested. It is priced at about the same level as the aluminum Salsa and, with a 1 15/16" blade and an FRN hilt of some 3 5/16". It is extremely light and the clip positions it so that it almost entirely disappears into your pocket, leaving only the very tip of the hilt showing. It is definitely a "low observable". Despite its size, however, I find it easy enough to open and, once I got onto the trick of the lock, very easy to close. The hilt is shaped very well to fit a hand and it keeps the knife indexed for its work quite nicely.
I have not actually seen a Kiwi to hold and to get any feeling of it, but it certainly looks nice even though it lacks a clip (a plus in some folks' eyes but a minus in mine).
