I haven't had a chance to use mine yet, hopefully I will be using them a lot here in the next couple months, but as far as using high quality knives I am sold on that idea. I used cheap fillet knives for years and then my wife bought me a custom fillet knife for Christmas a few years back, and it totally blows away the cheapo's that I have used in the past. We go dip netting for salmon every year and when you're fileting 50+ salmon at a time you become very familiar with your fillet knife and it doesn't take long to appreciate a high-quality knife.
