Caran D'ache Hexagonal 1.18 Mm Pencil: Lead Slipping

[elysee]

Greetings! The lead for one of my 1.18 mm lead Caran D'Ache Hexagonal series pencils slides into the pencil while I am writing. I have tried different types of 1.18 mm lead (HB, B, 2B, electrographic (my favorite as it is dark and similar to 2B lead in its softness)) but each slides into the pencil as I write. If I did not own several other 1.18 mm Caran D'Ache pencils (two of the Hexagonal series, two of the Ecridor series), three (3) 1.18 mm Pelikan pencils, five (5) 1.18 mm Montblanc pencils, and an assortment of other 1.18 mm pencils including Wasp pencils and Scripto pencils then I might believe that it is a problem with pencils taking 1.18 mm leads. However, that is not the case: the leads for NONE of my other 1.18 mm pencils slide back into the pencils. So, only this one 1.18 mm lead Caran D'Ache Hexagonal series pencil has this problem.

 

This pencil has the same type lead-advance system as current Caran D'Ache Hexagonal series pencils -- push button.

 

So, that stated (for clarity), does anyone have a solution for this problem? I like the pencil a lot due to its lead size and its lovely inlaid lacquer but having the lead slide back into the pencil is irritating. Since I have not had this problem with any other pencils (and I own a lot of pencils taking various lead sizes -- 1.18 mm lead pencils mentioned above, 0.9 mm lead pencils, 0.7 mm lead pencils, and 0.5 mm lead pencils) and since I have tried using leads of various hardness, makes, and ages, I believe that there may be a problem with the pencil mechanism. Again, I use the same types of 1.18 mm leads in my other 1.18 mm lead pencils, and none of these pencils have such a problem -- the lead does not slide back into the pencil and stays as placed for solid writing for all of my other 1.18 mm lead pencils.

 

I have tried to clean off the "teeth" that hold the lead at the end of the pencil but that has not helped.

 

I do not want to damage the pencil mechanism by attempting to dismantle it without some guidance/information. Has anyone had such a problem with a 1.18 mm lead pencil? Have you been able to correct the problem? How did you correct the problem?

 

Thank you for your consideration.

 

Happy New Year! : )
