I need to regrind my Tern knife from Byrd. It’s a slip-it design that really needs a thinner bevel. Saber grinds seem easier than FFG blades unless I want a compound bevel halfway up the blade. Anyone have any tips on how to do this and not make the blade look like my eyes were closed?

Chris,
I do what Cliff and Kyley taught me. Make a relief grind, then blend it with a felt-backed platen.
PS: edit: I mark the existing bevel with a marker or dye, then grind the relief grind until the bevel in like a micro-bevel, then I blend it in with a 3M Trizact A 30 belt.

Recently reground a Spyderco Chaparral XHP using an hard, coarsely conditioned (loose 24 grit carbide) 120grit Sic stone (i guess Norton Coarse India would also work ok), entire primary grind flat on the stone, oil and very high pressure to fracture the binder, going from 0.21 to 0.07 bte took about 20 minutes, but the steel was pretty hard to grind.
Then, sandpaper on firm leather (40 to 400 grit) to remove most of the scratches and refinish the blade.
Just be careful not going to the edge while grinding

Better than any factory knife I have ever owned, except for Opinels (about the same geometry)
I also reprofiled to less than 10dps at the end of the same session, that also helped a lot, if not more
The very tip is still a little bit thicker than the rest of the edge, but I didn't bother
