hi - thinking about getting a SIFU for an EDC knife - any of ya guys carry 1 all the time? any advantages/disadvantages?? i heard they had a propensity to open in your pocket due to tip up carry, is that true?? wanna get a larger folder, legal top 5 1/2" in tx - carry a spyderco matriarch and a BM AFCK, the SIFU would replace the AFCK. thanks for any info
