Don't think I know that one, have to look it up. Funny you should change to knives, I just got done blowing out my EDC emerson cqc7 spearpoint with some canned air. It was dirtier than I like to let my knives get, but oh well. Oh I also blew out my edc Mini-grip as well. TWO edc knives you say. Yup one for the sheeple and one for..well you know where I work. HOPE IT NEVER COMES TO THAT! But I like the security it gives me (at least in my mind).
