Brazilian and, if you can find them somewhere, Cuban & Honduran rosewoods, named for the fragrant smell of the cut wood, are reddish brown with darker - sometimes black - veins running through it. It grows in rather small diameter trees, especially compared with Brazilian mahogany, so the lumber isn't as massive as even some other Brazilian hardwoods. It makes great veneer - even thicker veneers - 1/8" or so - for guitar bodies. Small pieces for handgun grips and knife scales/handles are common. Another common wood often mistaken for a Brazilian rosewood is jacarunda - Brazilian cherry - which has a similar fragrance but lacks the dark to black stripes. It is commonly found as an upgrade hardwood flooring veneer. The rosewood scales on the cheaper 110s are usually Brazilian Rosewood - often at least for the ones I pick, with nice thick black contrasting veins.
I'm betting the pinkish wood used in the AG110's, etc, is the Brazilian cherrywood (Jacarunda), as I said, often called a 'rosewood'. I did think it was the Andaman Island Padauk, commonly used in violin bows. That choice faded when I couldn't find a knife with a small and slightly darker vein in it's scales - and Padauk usually has some small veins.
The Fiji orangewood looks like the darkened normally yellow 'osage orange from the American southwest. It is interesting to see woods I've used in small turned objects to vases and bowls for years now in knives. Some are sorely missing - true cocobolo - ranging from orange to reddish brown to black, often within inches. It's dust can trigger allergic reactions. Amaranth, or purpleheart (Brazil), is brownish when cut/sanded, but - within hours, will turn bright purple. This color is often darkened by normal, particularly oil-based, finishes - as are many other woods. Still, it is neat - finished at it's 'peak' with high VOC lacquer, it looks like a refugee from a bordello.
My favorite is still Brazilian rosewood - like the cheaper 110s. But, when my W-W puts those tins out, you bet I'll get a 110!

; and the government needs to take care of me and protect me from my own ignorance. I'm surprised Buck hasn't been forced to put a warning on each knife, "Blade is Sharp", duh, it is a Buck knife
