Need your advice one more time

I can quickly get my carbon steel kitchen knives sharp . There are some stainless steels that I havent had success with. Particuarly a Schrade extact American made. I can raise a burr. I dont know if im knocking it off. I use a ceramic stick to remove the burr and hone the blade.

At first it feels like Ive removed the burr , then as I keep running the blade over the rod , a bead will form on one side of the edge. A solid metal ridge. So I reshape the blade on a diamond stone repeat the process and it happens again .Im speculating that I am not removing the burr and instead bending it over . What do you guys think? Theres a couple of knives that Ive had this problem with.

I think you've diagnosed the problem correctly. From personal experience, I've found that the steel used in many of the Schrades -- 440A, IIRC -- wasn't heat treated to a very high hardness, and this leads to problems like you're seeing.

One of the best ways to remove stubborn burrs is to make a few very light passes on your ceramic stick at a much higher angle -- say, 40 degrees per side. Do this after your primary sharpening, just before you go to apply the final edge, and make sure the strokes are done with very little pressure (credit to BFC's Jeff Clark for this method.)

Do a search on Jeff Clark, he has gone into great detail about fixing this, I'd hate to try and paraphrase what his posts say and skip something.

Thanks you guys. That worked great. I knocked off the burr using the greater angle on the diamond stone , then finished with the ceramic rods back at the original more shallower angle. That metal ridge is gone and the knife is newsprint slicing sharp. Thats sharp enough for me.
