I want the shears to automate their creation, not their use as I already have a use for them which doesn't need shears.
That's not autocrafting or I would use them, at least I know of no way to make it automatically craft or to get items out of it. You can pump items in and then shift lick to craft a bunch but that's still manual even if it's made easier and simpler.
I autocraft with forestry workbenches just fine with GT tools, but I always make sure that the tool in the recipe is the exact same as the one available. Otherwise I'm pretty sure I've had tools mysteriously disappear.
