Replacement washers

Okay so I found a pretty cool new site. Well new to me anyhow. It is www.usaknifemaker.com . In the folding knife parts tab they have a huge selection of washers; nylatron, bronze, teflon, and the like. I am wondering if these would work on a straight, and if so what size would you all deem appropriate? I have broken razors down and cleaned them, but as of yet I have not put one single razor back together. :shrug:

Questions aside, if you haven't checked out this site then it is definitely worth a visit. I was stuck browsing on it for a WHILE! They have lots of great scale materials and just other cool randomness!
