Ceramic blades/scrapers

[Frank3k]

I saw a video of a modeler who used a ceramic scraper to cleanly remove flash on a part. It was impressive, but the fancy Japanese scraper was expensive (about $35, with just one blade).  I have a ceramic strip in my knife sharpening tool. It's bulky, but I used it on some flash and... it worked! So I ordered some ceramic blades from Amazon. One is a set of #11 blades, the other is a blade for the Olfa snappable cutter (both are white ceramic):



The edges are ridiculously sharp and can easily cut/remove flash and cut through plastic with no problem. The blades are fragile, but the results are impressive.

Have one of these in the kit for a while, yes they do work very well.

SMS here in Aus do these. Here

I have to say though, for the vast majority of the time, putting down a knife, to get the ceramic scraper out to do a small seam line, mostly never happens. I use the knife I have in hand

Same here.

That's why I have both front and center on my workbench, next to my primary fine cutter - a Swann Morton surgical blade mounted in a Bard Parker handle. I inherited two handles from my Mom's dental lab and they are the best handles I've used.This video by Paul Budzig explains:

I don't think a ceramic blade can withstand the forces needed to install or remove a blade from these handles. In any case, the Swann Morton blades are far sharper.

I've been  using a small steel engraver's scraper since the 1990s.  Does a great job of deburring on steel and an even better job on plastic.  Removes a lot of material and leaves a relatively smooth surface.  It lives in the rack with the X-Actos on the bench so it's always ready.  A similar tool:
