There are some around. I hope this isn't against policy to discus sources of supply. This is not exactly buying and selling.
Try "One Stop Knife Shop". I think they are still one of the pillars of Bladeforums. They show both the grey and BT with plain blades for $107.99, thir URL is
http://www.onestopknifeshop.com/store/emerson.html
The "Knife Center of the Internet" did have them for $109.95 last week. At this moment they are out of the of the BT plain blades. They had the plain BT blades and were out of the partially serrated BT blades last week. Perhaps check back, their URL is:
http://www.knifecenter.com/knifecenter/emerson/menu.html
I have made numerous purchases over the years from them and they are first class all the way.
Try "888 Knives R Us", I haven't ever purchased anything from these guys but guess they are okay. The have the plain blade listed for $99.99, no info if it is BT or satin. Their URL is:
http://www.888knivesrus.com/emerson/cqc7.html
Another source is OSO Grande Knife and Tool Company. I have never purchased anything from them but I suppose they are good. Their URL is:
http://www.osograndeknives.com/Emerson/cqc-7_wave.htm
They show the plain BT in stock. I thought the price was lower a couple of wweks ago, must have been mistaken. They want $129.99
Or failing in all of that try a Google search,
www.google.com and enter: CQC-7 wave knife
The resulting search should find arond 2000 or so references to sources. Hope this helps.
