Got a used kershaw 1475 whith bronze washers that was old and was really stiff to open. Took it apart polished washers onot 1500 grit sand paper and used buffing wheel to put a almost mirror finish on the blade and frame pivot areas. Used some 3 in one oil on the parts put it back together and it is still really rough to open. Any advice?

Not sure what your experience with knives is nor am I familiar with that knife, but....
Good bronze washers don't require a 'lube.' My first step would be getting it to open smoothly when dry if you really want to solve the problem. After that squirt it down with all the goop you want.
Did you check the detent operation well? Usually the detent has a lot to do with opening effort. Is it severe or could it be that it just needs breaking in again after your work?
It could be a number of things...bad pivot, worn washers, bad detent. If there aren't wear issues or tolerances out of whack somewhere it should eventually smooth out. If not, as a last resort you could contact Kershaw.

I'm assuming he meant PB.
Either way, if they're the original washers, he inspected and polished them and was careful w/ assembly it shouldn't make the knife as difficult to open as what he portrays.

Checked that thread and it doesn't seem to be what's causing the stickyness. Is it possible to polish too much where they want to stick together like when you put too panes of glass together and the stick to each other. I'm about to do a acid etch because I'm doing a rock finish on the frame. So I'm open to try something else. I sanded the pivot pin and it moves freely but that didn't seem to fix the issue. The brass washers are very small may I could find some replacements. I'll post up some pictures when I take it apart for the acid wash.
