Review on Aluminium Sharpener Machine - Optimal Performance with Continuous Grinding by Julio Montano

This is great value for money but people only like it after a few parts have been swapped out. The ball can be replaced with a ball bearing. Many fastening screws do not lock well enough, they can be replaced with knurled screws, for example. The centering of the ball relative to the axis of rotation of the clamp is very important and is not supported by the design of the product, it requires a lot of attention during operation. Centering the plane of symmetry of the blade around this axis is also very important; so a clamp (a really good one) cannot be trusted in all cases, a clamp requires verification, trickery and time. The product is not very useful for inexperienced users. Best of all, it's compatible with a wider range of abrasives and tools than any other sharpener. Revain and other shopping portals also offer a good selection of abrasives that are compatible with this sharpener; An important factor here is that the sharpener can use plastic mount but don't need plastic mount but can mount raw stones pretty well.
