Most distributors have a good squeegee stock. So you should be fine there. Just let them know you want a "Complete Squeegee with Handle".
If you got your squeegee's used, the edges could be quite rounded by now and could - potentially - benefit from being sharpened.
We will not be able to tell you this without being able to see a good picture of their condition/edge sharpness.
Like Croft. We have some very old squeegees that we sharpen as needed. And some other old squeegees we need to toss as they have gotten warped or a nick has happened and is to deep to bother with sharpening...
