I've been processing my own birds for one year now. It still takes me much longer than it should, mostly because my tools all suck. I have a collection of dull knives, game shears and kitchen shears that I shuffle through each time I'm processing. I bought a cheap filet knife for cutting throats, but it was dull after one use. If I was going to invest in one, maybe two, GOOD quality tools, what would you recommend in terms of knives, shears, etc.?
