It's a David Kikel.
Not at all
All of the Karellas I have seen were spelled out. Also, one of several logos I have seen on David Kikel cues does use the same font as this particular K, though it also has a Q beside it and a cuestick through it. My earlier statement about it being a Kikel was based on this font. He has used several variations of logos, but honestly I've never seen a single K on them.
