Klean Strip brand Strip-X paint stripper didn't work for me either on a Kershaw Blur.
Then I tried 32% hydrochloric acid (HCL) which is nasty stuff and dangerous but it stripped it in about 10 minutes. The problem is that the blade was left so dull that I had to spend a lot of time polishing with sandpaper anyway. Also the blade started rusting almost immediately. Not worth it for me so I got rid of the HCL. If I ever need to do it again, I'll probably just use sandpaper starting with 80 grit and progressing to 2500 grit.
