you're paying for a more accurately ground blade!...a journeyman cutler should be able to hold a .003" tolerance on his grinds, and a .0005" on the finish....the only machines that can come close to that require production runs of hundreds of thousands of pieces to be worth the set up time and costs. and i seriously doubt you'll see many holding that tolerance...you're buying the time and experience of someone who is maintaining thousands of yrs of knowledge regarding steel, heat treat, design, materials, construction methods, and processing. not to mention the yrs of education it takes to develop the skills...i've seen plenty of what these "college educated engineers" design, and you're better off finding a real cutler, and tellin him what you want the tool to do, and turn him loose!
