I purchased the R2 black as tsprof was out of stock. Long story short, the R2 is fabulous and rock solid. I love it and I can’t believe the other brands could be any better. It’s easy to set up and use too. I also purchased the Orion diamond and the boride t2 narrow stones. I highly recommend this guided sharpener. Customer service is excellent as well. I milled out a few pieces that I use with the R2 for making and sharpening gut hook knives. I would absolutely purchase again especially from Gritomatic.
