Material costs have virtually nothing to do with the price of a production knife. More important is the marketability of the brand name. Strider gets very high prices because the knife says Strider, not because of the costs involved in making the knife. Now having that name be worth that much cost something as well and that's part of the price.
To a lesser extent volume plays a part. There are economies of scale in making higher volumes of products. The companies complete overhead, including production costs of products, when divided by a bigger number of products will be smaller than when divided by a smaller number. So volume plays a part in pricing as well. Look at the Victorinox SAK's as an example. The company produces literally millions of units per year. That helps make the knives more affordable.
With custom makers it is a lot more complex. Some designs are very hard to make by hand and time consuming. As an example, a fixed blade knife machined integrally from a single piece of steel, guard and all, is expensive because it is hard and time consuming to make a knife that way. Polishing is a time consuming process, and so on.
All the other issues play into the equation as well. Famous makers get more for their knives than relatively unknown makers simply because of the name on knife. etc. etc. Have you seen what original Loveless knives get in the marketplace? It will take your breath away. Are the knives better than the knives of other makers? Not necessarily. Were they harder to make? Probably not. But they say Loveless on them.
While you don't always get a better product at a higher price, it is fair to say that manufacturers and custom makers know what their product is worth in the marketplace and can generally price them pretty accurately. If they don't the products don't sell well or sell too quickly. So if you see products selling as they should, it is a fair bet they are priced properly. Hope this helps.
