This filing guide is easy to use, this guide sharpens both the cutters and lowers the rakers at the same time. When you want to switch from sharpening from left hand cutters to right hand cutters you simply flip the filing guide over. The great design of this Archer sharpener ensures you get the correct angles every time.
There are files, and then there are real high-quality files. A good file is easier to get an edge on something; you will also remove less metal. Simple to use and now that I own this and the cheaper version, I will tell you the extra price is worth it.
