So that’s the spindle roughing gouge.
There is some similarities between bowl gouges (bg) and spindle gouges (sg).
In general, sg have less metal in them. They are sometimes made from round stock, sometimes flat then curved into shape. But the flute, the hollow centre, is always shallower than a bg.
This makes the bg much stronger, the shaft also always goes full thickness into the handle, giving it even greater strength.
In theory, an expert could follow a bowl with a sg. Because they know hot present the tool so as not to get catches, and can take very delicate cuts. It would take them a long time though. For you and me, it’s a recipe for trouble. You can use a sg on the rim of a bowl or platter for detail, otherwise a bg every time. I use a moderate fingernail grind at 45 degrees, as I like having the option the swept back wings to shear scrapethere is a great deal spoken about different types of grinds. And if you’re turning all day every day, then yes, I’m sure it makes a difference. And different grinds are useful for different tasks. My opinion, fwiw, is that as long as you have a sharp tool, and keep sharpening it, then you will do OK.
