Unique miter slide tool holder design allows the jig to be used more or less as a stone, guiding your blades effectively. 3、Enhanced Flexibility and Versatility: It is the replacement for the factory tool rest that comes with many bench grinders. The jig offers much more flexibility in terms of what you can get done than with the standard factory tool rest. The plate is offset for short chisels, such as Japanese or western butt chisels. 4、Convenient and Adaptable Mounting: The sharpening jig can be used with 6in or 8in bench grinders and on many belt sanders, grinders. It quickly and easily mounts directly to the bench in front of the grinder with a track design base and can be readily folded out of the way for freehand grinding if so desired. It can also be completely removed by loosening the large wing knob and sliding the jig from the track base. 5、Compact Design: The adjustable sharpening jig is compact in size that can be easily carried around and install for convenient use.
