These are channellock #424, the smallest tongue and grooves they make ( pliers like these used to be considered ignition pliers)
They Just come in handy, sometimes you I may need to hold a fastener in the front and one in the back, and my multitool pliers are generally for grabbing pulling and twisting.
They do some the little channellock pliers don't and the channellock pliers do something the multitool pliers dont.
It's just nice to have multiple bases covered and the maxpedition had some wasted space, these fit without adding bulk.
