Could This Be The Key?

As I was musing about the "DK" logos denoting David Kahn, Inc., I went back through and checked clips on several other lower-quality brands to see if they shared the same connection. Enter the Keystone, one that I’ve long suspected might have a David Kahn (Wearever) connection. 

The clips on each of these have a "K" on the clip, all right. Duh. It could be Keystone, but could it also stand for Kahn?
