You should look for a knife that you can use day in day out for all the jobs that come along. There are many different one's to chose from. All knife makers want to stand out from the crowd. In the old days there were knives that did everything. Long cuts, belt cuts, skiving, shaping, curves, straight lines, etc. etc. Knives were tools for workmen. They used them everyday to make their living and they were expensive. When they found one that worked for them they kept it. I know an old saddle maker who only ever used two knives. They did every job he needed to do and at the end of the day he left them in the workshop and went home. Nowadays people have collections of knives. They use a different one for every job they do and they have several that do the same thing in different sizes and styles. I started like the saddle maker, mainly because there were not many knife makers when I was young, and because they were too expensive to have one or two just lying on the bench not doing anything. Now I have boxes of them. All kinds from hand made to worn out veterans of the 1800's. The main thing is what kind of stile do you hold it? Thumb in centre or thumb in corner? Blades that are fat and have a ground edge are not so good for grip. It is good to be able to look along your thumb and see the point that the blade meets the cut. With a fat blade it's like having to look round a corner. The blade should not bend or be too thin. Learn to sharpen your own knife. It should really be stropped after every few cuts and put to the block at least once or twice a month. If you look after your blade, it will be safer for you. The most dangerous thing is a blunt knife. Osbourne make nice knives, Terry Knipp does too and they are both in America. What ever stile you choose remember it is a knife not a screwdriver. A screwdriver can be used and put back in the drawer for years without much ill effect but a knife requires a little looking after and respect. Do that and it will serve you well for many years.
First picture is thumb invented with hand over handle, second she's thumb in corner with hand under handle. This grip works better with larger sized knives.
And then there are Quarter knives.....
