I use Victorinox Fibrox (Forschner) knives. I like the large Fibrox handles. I use a longer curves one (about 5 inches) on the kill cut and a shorter one (4 inches) to do the other processing cuts. I use a pair of kitchen shears to cut off the head or other cuts where bones are involved. I advise using a cut resistant glove on the opposite hand for safety. I use needle nose pliers to pull out pin feathers when needed. I keep a sharpening steel on hand to touch up the knives between birds. These knives are available at a reasonable price and can soak in water before clean up with no ill effects. They are also dishwasher safe. Just Google "Forschner Fibrox" and you'll get lots of results.
