A friend of mine brought me a well built liner lock from Argentina with the only identifying mark etched on the blade - Japan Sourced Steel. I entered that in google & not much but a reference to South America. Sorry, I don't know how to post pictures on this site but it is pictured on the Knifeforum site, General Dicussion section. I asked the same question. Anyobdy familiar with this company (Japan Sourced Steel)?
