I have two custom knives (Ingrams) that I use for game processing and I really can't say that they are worth so much more than something you can buy from a mass manufacturer. What I really like, though, is the way that I can specify blade length and shape, and scale material, with the customs, and that actually has a lot of value to me. For example, I filled my elk tag earlier this week and will be breaking it down today. I have an Ingram drop point with stag scales and it fits my hand perfectly and is the perfect size for field dressing as well as breaking down the larger cuts. It feels like a scalpel and the scales help with grip when the going gets bloody.
I'm sure there are knives available from the larger makers that would work just fine, but it's nice to have something that is made explicitly to your specifications.
