Okay ill get the obvious out of the way first and foremost being that a custom usually but not always should have a better fit and finish. One thing I have not seen discussed very much is the difference in performance. Many will say this is subjective so here is my thinking. If we take a very good production company such as strider... politics aside. Lets say we had them make a fixed blade and had someone like nathan carothers make the same exact knife from the same exact material. Same grind same geometry only difference is the maker. Will the strider be superior or will the "custom" be superior. Ill even go as far to say we can use 3v at the same hrc for the steel as both strider and nathan have worked with it for a long while. Not to pick on nathan I just think in a meadow full of sheep hes one of the foxes if you will, clever measured and innovative in his approach. Lets even say its just a smaller run for strider where they can have better quality control. Will there be a measurable difference or if we wer handed both not knowing who made what would they be indistinguishable from one another? My last question is how many makers are really pushing limits and not just settling for if its not broken dont fix it?
