electric knife sharpeners

I’ve always been an electric knife sharpener guy. Yes it might eat up the blades but it’s been 25 years so far and my Henckels still look pretty good.
Now I see the Diamond Finger system that Rachael Ray recommends. I also read a lot of reviews. What do ya’ll think? How do you sharpen your knives? And if you prefer a steele, good on you: my arms get tired!
