Review on Sharpening Professional Whetstone Sharpener Non Slip by Jason Aukuso

Based on my observations this product claims to be a professional grade whetstone sharpener, but it seems more suited for beginners .While it did provide a decent sharpening, it was far from professional-grade. the non-slip feature did work well, but that alone was not worth the investment. As an industrial and scientific worker, I expect more from my finishing products and unfortunately, this did not deliver..
