There is a metal piece between the ball and the spring. It's almost like a fat nail because it has a narrower part that goes inside the spring. There is a small cutout at the back of the U-shaped hole the ball moves within, and this cutout allows the piece pushing against the ball to slide back enough to let the blade go through its full closing motion.
That little extra cutout is not centered on the spring mechanism. It is closer to the blade than the spine. On one side, that piece between the spring and ball scrapes against the corners created by the cutout area. If I rotate the tube piece it works OK (this just barely makes enough difference, you can't tell by looking), but it slowly works itself around and starts scraping again. I think it was in a good position when new, but now it wants to scrape.
Anyone else have a Poliwog with an off-center cutout (not the large U-shape one, but the smaller one at the back of the U)?
The nail piece only just barely needs to go past this cutout. You might not notice without looking close, but it's enough to make it stick sometimes.
