I'm not an experienced knife maker but I have done some math in my life time. It seems you under estimate the cost of knife making. Even the cheap route isn't that cheap especially if you are starting from scratch. A workbench, a grinder, a vise, sandpaper/belts, files, steel, handle material, pins, etc... The list goes on and so do the expenses. If you sell 10 knives at $100 each you might be lucky to breakeven on the initial start-up costs.
