When one has a hair clipper is often used, the lubricant is required for the blade, otherwise it pulls the hair. A lubricant is that tile as a product, but you hardly find in the radius of hair clippers ... unless you buy a new mower. Heresy! Once in a giga-hyper-market I found a small vial to a crazy prices. Now it can buy here is gigantic (I did not expect such a size to 118 ml) for an unbeatable price. To believe that Americans have a monopoly lubricant !!!! I have for years and years before emptying drops are enough for three each. I also took a can for my brother. I recommend this product high hand mower and encourages sellers to move!
