I have the top one, except mine has a black powder coating. Says "seki" on the side. It was issued to me in 2002, spent 3 yrs in south America and I still use it to this day. It's been regarded as their best fixed blade by the military for a long time. I know in some circles it's a collectors piece. I believe with the powder coating it called a "government agent". Pretty fitting. I think without the coating it has a different name.
