Our sharpening services can dramatically
increase the life-span of existing blades.

By sharpening blades to incorrect specifications, many other sharpening services actually reduce the life of blades. Renlaw’s engineers have an in-depth knowledge of which cutting geometries are required in each specific application, and also work to OEM specifications. The general rule is that more acute edges perform better when cutting softer materials but chip and break more easily, whereas more obtuse angles require more force to cut but retain their edges for longer and are therefore suited to cutting tougher material. A properly sharpened blade has a sharp-life comparable to that of the new blade, and can save your business thousands of Rand.
