Narrative:
Went to lavatory and upon returning, I entered the code in the door pad, first officer unlocked the door with the rotary switch, but I was unable to pull the door open. It had been written up previously as being hard to open, but as signed off after lubrication. I had tested it on the ground, but in cruise the ridiculous door knob design prevented me from getting enough grip to pull it open. I had to call the first officer on interphone and have him take off his oxygen mask, leave his seat and let me in.
