Sweet upgrade. I think the Work Sharp Precision Adjust is the first inexpensive guided sharpener kit I can recommend for beginners or budget minded who do not want, or cannot use stones freehand. Your stone holder extends function for grit progression, profiling with lower grit stones, and finer for chasing mirror polished edges. As a KME owner, I use your stone holder, bonded diamond and SIC stones to extend our kit as well. Thank you
