Not sure if this will display. If it does, one of these depending on the day and the tasks ahead. It doesn't so I will just relate that a Buck 112 Automatic has been my fairly regular choice since Buck introduced them but I also carry a LUDT by MicroTec, which is what I mostly carried before Buck developed the cojones to build automatic knives. I also carry a Buck Duke once in a while that was aftermarket converted to automatic. Very rarely, I will suck it up and travel to Commie Lands and then carry my very old Imperial Boy Scout knife. I no longer travel to Canada or Great Britain so I don't know or care what, if anything, might be acceptable to the dictators that run those countries.
