ex,
Nakano is correct to a point, (pun not intended). Flitz is probably the best all around polish out there. I have used it for years, (about 15). It is NOT a good preservative though. You MUST apply it on a regular basis. It will NOT protect for six months as advertised but if applied every couple of months, it will protect. It is also VERY easy to use which is a big plus. My method of protecting knife steel, (especially carbon), is to give your knife a thorough wipe down with Flitz. Polish it off and then give the knife a good rubbing with Renaissance Wax and then polish that off. An occasional wipe/polish with Flitz, will keep your carbon steel knife looking good. About every third or fourth time add a coat of Rebaissance Wax. Renaissance Wax really shines, (pun INTENDED), when used for polishing woods, and especially for leather and stag.
