I always liked this photo of Cold Steel in law enforcement use.
Mounted officers have begun using bokken for riot control activities rather than the more traditional long riot batons.
Presumably, this is because the katana trainers are longer and cheaper while being every bit as tough. That department wisely chose the unbreakable, weather-impervious synthetic Cold Steel Bokken rather than the more common wooden versions.
It looks to be the original 92BK with the smooth handle,
or perhaps the Bokken (92BKKC) or O Bokken (92BKKD) with the handle wrap removed.

P.S. - Edited to add: I thought I had another photo from a different police department using Cold Steel, and sure enough I found it. Clearly this one is an O Bokken. It's interesting that LAPD issued both wooden bokken and synthetics. I wonder if the wooden models began to fail and they replaced them with Cold Steel?
