Strop grease is suitable for polishing all kinds of knives! When the blade is not smooth and sharp, it is usually polished with the top layer of cowhide on the strop grease, which can extend the service life of the knife.
However, it may feel less smooth, so you need to drop a few drops of lubricant (such as oil) on the place where the sharpening paste has been applied, and polish a few times. This will make the rotating blade sharp and smooth. First, polish the coarse side of the grinding wheel at 50 degrees, and then switch to the smooth fine side. This will make the knife sharper. Apply oil on the place where the sharpening paste has been applied. During use, the oil is easily volatilized, so if it dries, add some oil to maintain the lubrication state of sharpening the knife.
