I have a 6" Pro. S Henckel that is about 5 years old. I have never had it professionally sharpened but I have honed it many times over the years (like 1-2 times a month). I have sharpened it myself using one of those handheld 2 stage sharpeners. I recently purchased an Electric 2 stage Presto Eversharp to sharpen it myself and it just won't get sharp. Any tips? I believe I'm handling it correctly to sharpen.
I use a bamboo cutting board (I know, they're not the greatest).
