You are going to need access to a power buffing wheel, to buff that antler, using jeweler's rouge. These things can be bought from some of the better hardware stores, or from the larger On-line suppliers. Harbor freight would be one place to look. Woodworkers is another. You can polish antlers by hand, but its long and difficult. You can also spray them with a good acrylic lacquer to get that shiny look. Make sure you can put a razor edge on that paring knife, that will hold the edge. Some of those blades have pretty soft steel, and will take an edge, but not hold it with any real use. Before investing your time, and a good antler to make a handle, make sure your blade is what you want. You can buy patch knives for less than $15.00. Check the suppliers, here, like Dixie Gun Works.
