You would have to be sure that the new phosphorus bronze washers were the same thickness and same inside diameter and outside diameter or slightly smaller would work for OD but no larger, especially on some models. Using a bigger outside diameter can affect the lock. Don't go there.
It isn't a matter of just buying some from a supplier and sticking them in there. If they are not the right thickness and don't have a 1/4" hole in the center you won't get em in there anyway.
PB is generally thought by many to be best. I don't use them. I use teflon or nylatron. Never had a single problem with them. PB can be smooth after a break in but not as good as teflon from the start or nylatron after they break in and they tend to break in faster than PB.

Yeah you can try that. Sometimes its difficult to negotiate a nice flat side though which can lead to blade play. A lot of folks think they can just buy a washer they see and stick it right in. It isn't so prevalent with EKI since Ernie uses thicker washers than most but with many others I get for work I can tell in a matter of a few minutes they replaced the washers that came on it. Some are much wider at the pivot than the spacer in the rear for example. I think many just think there is some set standard they all live by or something. I was just making sure in case he is not as much a knife nut as some of us that hang around here are you know? :thumbup:
