Great sharpener
I’ve been using the steamboat sharpener since the late 90’s. It’s easy to use and I’m able to get my knives razor sharp fast with little effort and the customer service is great. I have an old base from 1999 with the original 1/2 in rods, I ordered 2 3/8 inch premium rods and they fit perfectly in my old base and brought it back to life. .
