From the reviews: "In general, a decent sharpener.Almost all of aluminum and stainless steel, which is logical for wet turning. The angle of installation of the blade is fixed at 9 degrees, if desired, by messing with the screws, you can change. The angles of setting the stone are 9-34 degrees horizontally ".
"The machine is quite good, I expected the worst.For its low price, the quality is acceptable. Oddly enough, nothing dangles during operation, no backlash (after preliminary broaching by itself). The knife sits confidently in the clamp too. I use another clamp, I also equipped the machine with an electronic level. The sharpening of the knife began to occur without dancing with a tambourine to a very acceptable sharpness in a minimum time. Recommend!"
