I am pretty much edcing a Kershaw Emerson cqc 4kxl. I like it, but the teflon washers suck. I've already replaced them with the washers from a Kershaw Starter, but it still won't really stay centered. I'm wondering if aluminum/steel washers that I can find around the house would be a good idea to use, or if it would mess it up. I like being able to flip it open, and the teflon does work well for that.
