Some could be quite nice tools if they were made a bit better
Great point K_G I had to have another look at the multi tools to see what you were talking about but That it is stupid having the hatchet facing your wrist when using the fold out tools
I saw a YouTube video years ago where someone was testing hammer and hatchet multitools. The guy in the video was bleeding after one of the "plier" tools popped open while he was hammering, causing him to hurt his hand in some way. Then he almost cut his wrist with the axe blade before he gave up on sawing through a little branch. It's kind of sad really, I feel like there is a place for a small hammer multi tool to exist. I've just never seen one with a genuinely good design and quality.
WeAllJuggleKnives had a review of a hammer multi-tool that was decent. It was a claw hammer design. Hammer and nail puller, no useless axe that is only good for cutting the user. Delko maybe? Something like that, though it can surely be found under multiple brands.
This is the photo of the pterodactyl multi tool I saw online. I think it qualifies for this conversation.
In the "real tool world" there have been multiple iterations of combo tools that combine a hammer with other tools. One common and fairly successful one is the so-called fencing pliers, or fencing tool. Many's an hour I've regrettably spent wielding one of these:(Image removed from quote.)
I never understood those until I was at a friends house helping him put up a quick temporary fence to keep his livestock from escaping. The "fencing pliers" are fantastic if all you are using it for is twisting and hammering bailing wire on a fence post. It's a great specific tool. But try using one to get to a bolt inside an engine compartment or some other enclosed space. The hammer and the plier jaws are compromised by each others presence in most cases where you would only need one or the other.
