all the newer ones I've seen are plastic, some of the older ones that I have seen were the craftsman or rebranded craftsman. First time I saw one I was wandering why they had a mechanic in the ER. Figured it out fairly quickly that it was not the same stuff in them. I use a bunch of stuff from doctors and dentist, but it is small stuff, Hemostats and others as clamps and stuff like that. Dental picks for removing burs etc.
