3. Adjustable Replacement Tool Rest Sharpening J
Our Rating

- The Adjustable Replacement Tool Rest Sharpening Jig will allow you to locate all the basic sharpening positions with your bench grinder (grinder not included). The unique miter slide tool holder design allows the jig to be used more or less as a stone, which easily guides your blades, turning tools and chisels. Solid aluminum construction provides you with a smooth sliding, side to side action when sharpening.
- The sharpening jig works with most power or hand grinders that has or had a tool rest. It is the ideal 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.
- The Sharpening jig can be used with 6″ or 8″ 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 style 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.
- Another great feature is that the jig can be adjusted forward and backward for just the right angle. Some aftermarket and expensive tool rests don’t move and adjust in this fashion. This can be very limiting your ability to be accurate with your angles. The platform straddles wheels up to 1″ wide. The Jig also now includes internal lock washer for even more stability!
- The unique ratcheting handles lock the adjustable rest solidly in position and can be moved out of the way after locking to keep from accidentally bumping them. You can easily move the tool rest from one grinder wheel to another or quickly remove it from the bench when not needed for grinding. Some assembly required. The bench top wood mounting screws are included.
