I'm preparing my sides for routing by scraping and sanding them
smooth. The scraper is creating a ton of scratches on my black plastic
end wedge. If I sharpen the scraper again can I go over the scratches
and make the wedge look like glass again? Or is there another method?

Yes - scrapers rule!! I also use a single edge razor blade. Always set the blade at an angle so you shear cut.

I find a razor blade to be superior in this effort to take down bindings and purflings and rosettes

Heck, I have been using a razor blade as a scraper to get rid of the ridges in my finish before I start wet sanding. Saves me a lot of time when I have to sand a brushed finish. Works on pore filler too. Razor blade scrapers are fantastic!

I saw a video of a guy who sharpened his scrapers by clamping it into a bench vise, then using a mill bastard file on the scraper. No burnishing, no turning a hook, just 3-4 passes with the file, and off he went. He made great fluffy shavings from maple, mahogany, etc. So I use that method now. It is really fast to sharpen my scraper that way. I have also used the shaft of a screw driver to burnish the edge when I want a smoother finish. Sharpening a scraper was one of those tasks that seemd daunting when I began building. Now I know. And knowing is half the battle.

Now I know. And knowing is half the battle. G.I. Joe!

I use the same method of using a flat file to sharpen my scraper. You might want to spend more time on it if your using it for a final surface prep but for most things it's fine.
