1)Adjustable Angle Device: Sharpening angle can be easily adjusted from 0-55 degrees.The rotation of the knob causes the gear to rotate, in 0.3 degree smallest measurement.

2)360 Degree Rotation Device: The Bearing can be easily rotate in 360 degrees .The rotation device increase the grinding angle range, improving the grinding efficiency.

3)But I want to remind that the inner diameter of the fisheye bearing is 6.0mm, which is suitable for the passage of stainless steel rods below 6.0mm. According to our communication with Ruixin Company, Some of the rods of Ruixin Pro RX008 purchased before March 2022 The diameter is more than 6.0mm (about 6.1mm) so our suggestion is: it is best to measure the diameter of the stainless steel rod of the rx008 in your hand, and then make a purchase decision. Thank you for your cooperation and happy shopping.

4)The overall structure is composed of aluminum alloy. The surface is anodized.The bearing is made of stainless steel .
