Keeping your razor sharp with a strop is the basis of straight razor maintenance, but over time the leather strop itself can dry out and form cracks. These cracks then prevent the strop from giving the razor a smooth surface and can result in poor sharpening and blunt edges.
Using a stropping paste regularly will keep your strop soft and smooth and will ensure your straight razor stays as sharp as possible.
Simply smear a small amount of paste from this 5 ml tube on your strop before every use. A little goes a long way.
