*blinks* What are you using to sharpen it? I've never seen a 1095 Ka-bar that didn't want to take an edge.
I use a diamond pocket rod to touch up in the field, and a stone Lansky (ok, I'm lazy) at home. If I have the time and inclination, I sometimes get out the big Arkansas stone and some oil, but that is only if they got used hard. I do have one that I sharpened with Japanese water stones when I did my sharp sword up, but hair spliting is a quirk in my inventory. I have one that I keep fairly dull for throwing, but the rest are all arm shaving sharp.
