It all depends on how you use the knife. If you use it for normal cutting there is no force applied forward on the handle. If you on the other hand shove the knife into something/someone the CSI guys will find your blood on the blade (generic CSI episode

) and you will have a nasty cut in your hand.
If the samis in northern europe would have considered it to be a dangerous design, why have they made the same type of knives for hundreds of years?
It is actually until quite recently the average Mora knife got any kind of protection. For almost a century they had a red wood handle with no finger guard whatsoever.
I think it is a culture thing. In Europe people CUT things with their knives and consider it as a tool. In the wild west a knife was also a weapon to defend the user, to STAB bears and indians and other dangerous things so then the finger guard came in fashion.
Buy the knife you want and learn how it behaves. All knives have different personality. Some are nice, soft, helpful and almost female, some are hard, macho, angry, masculine and some try to be macho but only has the gadgets but
Some knives likes you and some dont. It all depends on how well your mood,hand size and the strength in your separate finger muscles compare to the person who designed it.
