Here is the reply I got from Bernard Levine on this knife:
Edges was a collector oriented tabloid published by Blade magazine, trying to compete directly with Knife World when its owner would not sell. I have not seen it in a long time, don't know when it faded away. It never had much in the way of content to offer. It tried to offer 'stock tables' of current knife prices, but pre-eBay these had no basis except wishful thinking on the part of a few dealers.
That looks like an OK knife. Is there a country of origin marked on them? If not, they are likely by Camillus, which made a lot of that pattern under a variety of brand names. Alcas made some of that pattern, too, but usually with fancy etching by Aurum or Baron.
To tell bone from plastic, look at them under magnification, even just reading glasses. Bone has lots of tiny pores (Haversian canals) while plastic does not.
