I used to have the same problem as you. Couldn't get a knife good and sharp to save my life. I tried lot's of different methods like you. Lansky, stones, files, you name it. I even bought a "good" electric sharpener. Waste of money too.
Buy a Spydero Tri-Angle Sharpmaker. You won't regret it. You can shave with every knife I own. Easiest and best sharpening system I have owned, and I have owned several. Several good ones too, they just didn't work for me.
