Okay, so I got myself a Spyderco Goldstone for Christmas. I'm having some real problems using it, an I need help. Everytime I use it, I develop what feels like a bur or lopsided edge on my knives. I'm considering selling it and sticking with my sharpmaker. I'm really starting to think that I'm absolutely useless at sharpening, I either have this problem, or the knife comes out dull beyond belief. Is there something I'm doing wrong? Can somebody help me?
