Hi Danielle, I carry a knife based multi every day. All outside tool access of course. I have a few plier based multis, but don't like the kinds of pliers on them much. When I use pliers I generally reach for Vise-Grip locking pliers or slip joint types. I always have slip joint pliers handy. Bigger Channel Locks are available in my tool boxes. I actually just as soon carry internal tool plier type multis. Something not too heavy. If I was forced to buy another plier based multi, I would buy a Leatherman Bond. Old school internal tools. Not too bulky. Good to see you back. Are you going to do some movie reviews again? Best wishes. Gary
Like David, I don't have a preference. Most of the PB multis I owned before and during my enlistment were of the inside-opening variety. The Squirt E4, which is one of my favorite Leatherman tools, is an inside opener. But I must admit that it's pretty convenient to open the blade on a Wave or a Signal one-handed, with no unfolding.Being that Danielle is in the UK, it may be worth noting that all the outside openers I can think of right off the top of my head have locking blades. That could be something else to keep in mind.
I have a tiny version of my cheap chinese tool I've had for years, possibly the size of a Leatherman Squirt, PS4 which doesn't lock but has inside accessible tools.
Maybe try a Gerber Dime? It's about the same size as a Squirt, with outside-opening tools that don't lock. Quality control and finish on mine definitely left a little to be desired, so hopefully they've gotten better since 2016.
