I was using other guides with similar design and I would fail for uneven pressure. Chisels would not end up being 90 to the blade. My OCD is cured with this one. There is small play between shaft and brass wheel, but results are awesome.
The wide rollers make this jig much more accurate in sharpening my chisels and irons
The moment I opened the package, I knew I was looking at a well made, well designed, meticulously manufactured product. Set up is easy with a combination square: the alignment lines not so much. Got my first hand plane iron sharpened in no time at all. Overall, very satisfied with my experience.
