Noisy Dodo

[Django606]

Hi guys, I love my Dodo, blue PE. It is a great cutter and has a great grip. I noticed VERY slight side-side blade play, so I went to tighten up the pivot. I experimented with different settings, and after a little bit, I noticed the knife had a literally choppy opening. It would go about a 1/4 of an inch and the stop, etc, etc, until it was open. It did this even with the pivot screw really loose. I decided to take the knife apart. (BTW, when I first got my Dodo, it made no sound at all, you could hear the little clicking of the ball sliding onto the tang when you first open the knife)

I cleaned everything, and put a little grease in between the blade and washers, wrote with pencil on the back of the tang where the ball rides, and put it back together. The choppy action was gone, but the knife makes this sort of gritty, sliding (hard to describe) sound when I open it. Pretend the closed knife sitting spine down on a table. The knife makes the noise when the blade is opened at about 20* and at about 90* open.

I think the noise is caused by the blade rubbing against the G-10, as it only makes the noise when I open with my thumb one handedly and not with a thumb and finger two-handedly. It still makes the noise two-handedly at 90*, but not at 20*.

If anyone has some tips on how to stop this and restore the Dodo back to its original, quiet state, please share them

I think mine made the same noise for a little while. If I'm not mistaken, the problem resides within the lock springs(one large one around a smaller one) themeselves. It may have to do with the terminal ends of the springs ending in a single point, like a keyring. Anyone else have any insight?

Playing with my blue Dodo, I remember when it made a bit of a louder sound on opening and closing.

At the time, the "piston" was a bit sticky in its movement. Turned out a bit of something was in there somewhere. For a period, it would actually stick in or out, renendering the lock inoperable.

After a time, the problem went away. I did a lot of open/closed cycling, though.

Since you had yours apart, I doubt this is it (but you never know, so I'm mentioning it).

I suspect you could put one shim-washer for the blade in and it might stop the noise.

I'd not try lubricant, as I want the lock FOD free.

STR probably has a better idea and/or more knowledge, though.
