No fishing hooks! Makes sense since SEAL DEVGRU Team 6 members can catch a Mackerel with their bare teeth.
Actually I think these are copies of the same shiny PSKs which were ordered for the Navy SEALs. Even the SUMA metal container supposedly has a velcro patch for a moral patch

These PSKs seem to be genuine copies.
