Scraping tool steel

Hi.
My question.
Can I scrape a piece of tool steel with a metalworking scraper, do we have such a thing at the space.
I am interested in flattening two convex surfaces which are supposed to mate.
I am open to suggestions.
I am pretty confident I could flatten the metal using a dremel and a grinding bit if I work incrementally, continuously checking, marking and grinding the high spots. It will take a long time though.
What are the options?

How big is it? Could use the mini mill or CNC - I’m not sure if we have a flycutter but I was planning on buying one soon

It’s a 60mm wide blade and chip breaker. Both the mating surfaces are convex. The blade is approximately 200mm long, the chip breaker is 145mm long.

Would tool steel not wear out mill bits pretty quickly?

The first replacement blade I found was 60 HRC so we’re in abrasives territory. The easiest way to do this is the surface grinder at SMEE. Might be best to tag @metaltechs
They can be hand lapped as well.

According to Google and the engineering forums I looked at you can use a fly cutter on 60 hrc steel.
Surface grinding would probably be easiest.

Yeah good point, and that mini-mill isn’t really up to the job even if we used a cutter with a carbide insert
