Cody, good to see you’re thinking of one of the “little” things that can make a big difference in success. As kid over 50 years ago, we used fine cut three corner files from Dad’s tool box to put a point on our Johnson’s Silver Minnows. I have yet to find anything better. A Luhr Jensen hook file works as well for larger hooks but can be a little cumbersome on tiny jigs.
File the point facing away from you, from barb toward the tip. For example, holding the jig with the hook facing upright, point facing away. Hold the file, parallel to the hook with one flat face of the file straight up and down. Before your first stroke rotate the face of the file until you have maybe a 20 degree angle. Now holding the jig very firmly take a smooth stroke from barb to tip. You should be actually cutting away a small part of the barb and creating a smooth bevel all the way to the tip. Imagine trying to create a diamond point spear head to penetrate armor. After you cut four bevels on that hook point, turning the jig for each bevel you’ll be done. The barb will still be there, narrower but still there, with a long narrow beveled point that will be very sharp.
