The green boxes are hen and rooster I think...
Hen and Rooster used to be a good brand, made in Germany and well respected; some of the newer ones are imported from China and not worth much. Some may still be made in Germany, or at least assembled in Germany.
I think there is a crap ton of Master Cutlery also. In another bedroom I came across a lot of Marine style swords. Obviously there not original's but I dont know if there some foreign knock offs or some sort of "official" approved reproductions.
Most likely more flea market table filler, sorry to say.
Buck is another brand I see a lot so I guess I lucked out there.
Buck knives that are older, less common, or made in the USA will find a home with a collector or user. No problem. But many of the current Buck knives are made in China, and although they're generally functional as knives and come with the Buck warranty, they aren't sought by collectors and generally sell for very low prices.
