In German, the K would be pronounced, and the z would be hard, as in "pizza". The last syllable is a schwah so it's more subtle or diminished than the last syllable of "pizza".
(just jecked it their website)
Knize goes back to an austrian tailor named J. Knize who lived in 1858.
So his name would be pronounced with a strong "K"
/K/-neez-a
the last /a/ is hard to explain to non german speakers.
You can imagine it like the "se" in the wort "separation"
So it would be /K/-neez-/se/
The word Ten goes back to the royal english game polo
wich to Wolff and Dryden (former owners of knize ten) had been a symbol oh elegance.
The highest handicap in polo is called "Ten".
