Just a quick question on belt grinders. How much time do they really save? I tried a 1x30 for one knife then realized all I needed was a steady angle and went after a file system for my bevels. Tonight I hybridized the ideas to clean up some plunge lines and it took a lot longer than I thought to take the steel off. Is a 1x30 that much slower to remove the steel? I know I go through the belts quicker than a 2x72 but it seems like it takes much longer to work than a file. I thought it would make up in hand sanding but that still takes a long time. Am I doing something wrong or just saving 1500 bucks? I am working on a 3/16 stock piece instead of the 1/8 pieces I have been using for small blades but I am surprised at how long it takes for 80 grit belts to make a dent. Thanks for any help.
