Has anyone out there ever hear of a Kershaw KAI 2420??? It says JAPAN on it?!?!?!? I picked this up today at a garage sale for $3.00 and was wondering if anyone has any experience with them? Reviews? I did a search for it and nothing came up. Just wondering if this was a good idea or not? It will never replace my EDC Benchmade Barrage, but this may become my secondary (hey can I borrow your knife and use it as a hammer) knife. Any thoughts???
