The Super Scraper
Here's a tool I've been using for years. It's called the Super Scraper. The original intent was for metal working, deburring, rust removal, etc etc., but I use it in the shop pretty-much on a daily basis. The owner of my local sharpening service invented and manufactures the scraper.
The Super Scraper is made by brazing (I think that's how its done) a square section of carbide, a little over an inch long onto a steel plate, then riveting that to a robust wood handle. The carbide is as sharp as any new router bit and readily takes the finest dusty shavings in hardwoods and exotics, all the way to a curly plane-like shaving. It also really shines as a glue removal tool, since it wont catch or lift the wood grain like a putty knife or chisel. I wait until the glue gets pretty rubbery, then away I scrape. Works great. I also use the Super Scraper to tweak joinery and for scraping areas where I want a dead flat surface. Card scrapers are a great tool, but this guy takes the lead for critical flat scraping operations. I like to think of it as a single-tooth joinery float. I made one modification to the tool by grinding back the front shoulders of the handle to allow a bit less angle of attack.
Pushing the scraper gives decent results for hogging off lots of material, but it can be prone to digging in if I'm not careful.
These are shavings right off the scraper.
A more controlled way to work is with the scraper in a vertical position, grasping firmly with both hands and pushing.
The carbide cutting edge really shines on dense woods like ebony.
Sharpening the scraper is fairly easy. Over about 8 years, I've touched it up only a couple times on a fine diamond stone. The manufacturer will sharpen it for free for the life of the tool.
Drop me an email of you're interested in purchasing one.
