Best Steels and Geometry for Scraping

[Vamais]

Recently I've been doing a lot of scraping plastics and wood, to the point where I believe that scraping is responsible for most of the dulling I'm experiencing.

Any thoughts on what steel (from Spyderco) would retain its edge the longest in these situations? What about edge geometry?

Tool steels, this is similar to what a lot of them are designed for, though they may be heat treated differently for knife applications.

A lot of scraping in wood working is done with “cards” made of tough tool steels, with pretty high angles.

So maybe something tough like a H1, ABE-L, 4V at 30°+ per side.

At least this is what I think of when you say wood scraper.

I have a D2 civivi Brazen I use for scraping stuff, I find a tanto is best for the job

Geometry will make all the difference, much more than steel type. The card scraper pictured above is pretty soft steel, soft enough to roll the burr that does the cutting. Maybe low 50’s on the Rockwell C scale.
