When European knifemakers are mentioned, Fred Perrin immediately comes to my mind. I own many of Fred's pieces, and in fact have a very original piece of his on the way to me this coming week which is a collaboration between he and Laci Szabo.

(The best of both worlds. Sorry, I could tell you more but I'd have to kill you)
Anyway, Fred is an absolute artist, maniac, and madman when it comes to instinctive fighting blades. Of course his "La Griffe" (The Claw) design is responsible for the success of Ernest Emserson's La Griffe neck knife, which is Fred's design. No disrespect intended towards Ernie, but Fred's Griffes are MUCH more wicked and well balanced.
Fred makes blades for up close personal encounters. His pieces are instinctual, and become an extension of your being. Obtain other pieces because they appeal to you, but obtain Perrin's to save your ass and you'll be just fine.
Fred doesn't have a BF presence, but his friend and associate "Nemo" does. Do a search of "Nemo" and you'll find many fine reviews that he and Fred have done. Nemo has also produced a website for Fred here
http://www.geocities.com/Hollywood/Set/2292/main.htm . It loads somewhat slow unless you have a fast connection, but it's well worth the wait.
Here are a few of my favorite Perrin customs:
