I guess by quality I am asking about basic Kit materials, as well as grinding and heat treating.
It seems that you are saying that a Kit by Darrel Ralph would have components with the "raw material" quality of a Darrel Ralph custom knife? The difference would not be in the components of a similar Darrel Ralph custom knife, but in the design limitations, and skill level for altering and finishing the kit?
Or, for instance, are the Kit components designed by Darrel Ralph, but produced by a "factory" rather than hand fabricated by Darrel Ralph, and thus of somewhat less quality?
Again, thanks for helping me out.
You have to be realistic in your expectations. You kit knife will be "DR" designed, and "DR" inspired, but not a DR knife. It is a different animal. They are both knives, but I would be the similarity ends there.
DR himself can dictate any steel and heat treatment he wants as he is in the knife making stratosphere, no longer worried about price points. With years of making quality knives of his own specifications with his own hands, you are buying his knowledge of assembly, material selection, and quality of said materials. That includes everything used.
A price point has to be met on the kit knives. Someone that wants to jump in and make a knife isn't going to spend a couple of hundred on a kit. So you get AUS8 bulk heat treated blades, bulk cut handle liner and scale materials from a usable but not the best stock, and screws of unknown origin.
If you go to the knifekits site in particular, you can see some amazing work that has been done by folks that buy those kits. No kdding... amazing.
But in the end, is it a DR knife? No. In the end, you still have the lower quality blade (and that's what knife is all about, right?) in a handle of pretty good materials. If you go away from the kit, you can upgrade handle materials, bearing materials, etc., and customize as much as you want. Your finished product may look great and perform quite well, but it still won't be a DR knife.
When you get a DR knife (he's just one example) you are paying for a dedicated professional with many years of experience behind him SUPPORTING himself with his efforts. His reputation and livelihood depend on the quality of his product. You are paying for that time and experience needed to watch over every aspect of the knife making process, select every piece of material used and to make sure in the end it all comes together perfectly.
When you get to that level of commitment and experience, you will no longer be interested in kits. The DRs type knifemaker's standards will be your new high standards, and while the kits will have served their purpose, you will have moved on.
As always, just my 0.02
