I own and have used the havalon piranta model and it has its place. I like to keep one in my pack as well but would never use it as my main blade as they are more of special purpose knife. They are great for skinning and precision work such as turning ears and splitting lips and nose in prep for taxidermy. However for field dressing and boning a regular drop point of good quality is my preference. If you try to get too cute around bone with the havalon you will slip a blade off the thing, but they are not meant for this type of work. When used properly they are a very useful tool.
