As always, its different tastes for different people.
I've gone to using various-shaped utility knife blades for final scraping/prep.
e.g. carpet knife blades, modified utility knife blades, carved scalpel blades, and my latest MVP go-to discovery: the round replacement blades for circular fabric cutters.
Sharp right out of the wrapper, and gets many of those pesky concave surfaces around lock panel transitions and cheek pieces.
You can rotate it and slant it for various contact profiles.
Try the test yourself: With low-angle lighting, sand with 320 or 400 grit, then go over the same area, with a light hand, with a sharp blade (hooked or not) with the grain.
I believe you'll see the difference immediately.
Again, different tastes. The barely perceptible flats left by these blades don't bother me.
Tool marks can add character to many rifle styles.
If you're going to Dixon's this week, try to catch Mark Wheland's seminar on scraping. I learned a lot from it last year. Its Saturday I believe.
