Here are some woodturning scaping tools.
You don't see the handle, but obviously, there is one for each
The blades are HSS made out of pieces of jointer blades.
I cut them with the dremel with a high speed cutting disc, that goes pretty well.
I have plenty of different shapes, the one at the top is for scaping the bottom of bowls (you need to hold the handle very strongly, they are prone to engage with the wood)
The one at the bottom is specially shaped for making captured rings or finger rings.
It's not clearly seen here, but as I don't know how to drill in HSS (or exactly I don't want to bother with that), the screw is not inserted in a hole, but in an open groove. The result is the same, and you don't even need to un screw completely to change the blade (for the lazy man).
