My service 14 will always be my favorite - it stays in it's own category. Other than that one I would say any Model 1 because it's the Model 1. My 5-8 because I love that 8" blade and choil. The 19 has become my favorite hunter and the unique blade shape / grind lines really stand out in the crowd. I'm sure whatever I buy next will have to be one of my top 3 also..
