Received my Kf 4 today, overall I like it. I wanted something smaller and lighter than my SOG for EDC and this will do the job. I'd prefer an awl like on a SAK, but a little grinding should fix that. To cover the can/bottle opening I added a P-38 and a double wide bottle opener from Bison Belts. The lanyard attachment can be flipped in or out, so it won't dig into you if it's not being used.
