I've always found screwdrivers really useful on a multi-tool. Infact I wouldn't buy one which didn't have one.
Leatherman steps this function up with the introduction of its new Ratchet Driver. Not only does this extend the length of it's screwdriver but it also makes it ratchet. Ratchet screwdrivers are always easier and more pleasant to use.
Another massive plus is this extension allows standard 1/4 hex bits to be used as well as Leathermans own flat bits.
The Ratchet driver fits into the screwdriver slot so only works with Leatherman with that fitting. For us that means that this is only compatible with the Skeletool that we stock. For me this is the tool that I carry when out on the mountain bike and when snowboarding - and is also the tool that will benefit me the most from having a better screwdriver function.
It's also compatible with the following Leatherman multi-tools:
Charge®+ TTi. Charge®+. MUT®. MUT® EOD. Skeletool®. Skeletool® CX. Wave®+, Surge®, Skeletool® RX, Signal®, Heritage Charge®+, Heritage Wave®+, Black & Silver Signal®, Black & Silver Skeletool®, Black & Silver Surge®, Black & Silver Wave® +, Topo Signal®, Topo Skeletool®, Charge®+ Forest Camo, Super Tool® 300M
