Rust Erasers: These are affordable and versatile. I use them to clean whetstones and remove scratches on knives when they load up. They are also excellent at removing rust.
Budget Sandpaper: You can spend a lot on sandpaper, but I use what is on sale or budget-friendly for these projects. You can pay over $100 on sandpaper to get the grit levels needed for this project, so it is better to choose a budget option. I start at 240 grit when the knife has a lot of deep scratches and go up the grit range to 1000.
Atoma 140: This is my preferred method. It removes materials quickly but is more forgiving than the bastard file. Also, making micro-adjustments is easier with the diamond plate. The Atoma 140 is what I use for 99% of my restorations and repairs.
Favorite Sharpening Kit: Once you are done removing the chip(s) and are satisfied with the cutting profile, you can move on to sharpening and polishing your knives as usual.
Koyo Polishing Compound Blue: The Koyo polishing compound gives the knives a mirror after you finish sanding with 1000 or 2000 grit sandpaper. It does an incredible job of bringing out that extra sparkle on your blades.
Koyo Polishing Cloths: These work incredibly well and last about a dozen uses per sheet. Very handy to use when you do not want to deal with messy compounds.
