Cheers MB, personally not a fan of the Gerber Multitools. I find them fairly bulky for what they are.
Currently I have 3 different Leathermans I use, those being the Sidekick, Wave and OHT (One handed tool) with all 3 being ideal in their own way.
The Sidekick is a no frills Multitool that's sturdy and will suit most people.
The Wave is sort of like it's big brother but heavier duty and more functions and includes additional tools and optional extras like full 42 bit driver kit and driver extender. This is the model I carry daily and is always being used around the place.
The OHT includes a flick plier system, all blades are external including a seat belt cutter, that stays in my EDC bag for out and about and in the troll.
There's 2 larger, heavier duty versions being the Charge and Supatool but they are fairly pricey and have a lot of pieces that can be replaced when worn out instead replacing the entire tool itself.
Most Leatherman models will have some items that can be replaced which will differ from each other.
Mainly it will come down to how often you plan on using it and what you're intending on using it for as they can vary from around the $70 mark ( Sidekick / Wingman) right up to the $300-400 mark (Charge etc).
There are plenty of them out there with varying prices and packages depending upon budget.
The pancake sheath has the model shown above and a more rounded version of it that can be wet moulded to fit the chosen Multitool.
