I am seriously considering getting one of these two knives. However, it seems that they both are pin constructed. I want the lighter weight these models offer but am concerned about not being able to open up the knifes as both of there locking mechanisms can get very gunked up with use. I need some advice. How do you keep you knives clean with thenpin construction or do you just always opt out of pin construction and go for the g10 (which I an really reluctant to do)?
