>Par for the course.
>Pick it up with our left hand, let whatever aci'd left take care of whatever glue might be left.
>Have a more careful look down that side tunnel, burining away any residual webbing that might still be obscuring our view/passage.
>You did not pack for spot acid-repair, sadly.
>You pick the kunai up with your left hand, finding it easier to simply put your whole body into the motion rather than fight with your arm to bend properly. You fingers fumble a little as they grasp at the handle, but it feels secure enough in your hand once you pick it up. Gripping it does sting, but probably no moreso than unpleasantly hot water, and the sensation starts to fade quickly.
>You go back to the side tunnel and set to clearing away the rest of the webbing. With a frown, you note that your torch has burned down significantly from when you lit it, although you think you can get a little more use of it before you need to light the second.
>Shortly enough, the barrier gives way entirely. Looking through, there appears to be a small chamber on the other side of the tunnel, no more than 10 feet away. You can't see much of it through such a narrow space, though you think you see thick webbing along the visible wall, not unlike what was blocking the passage.
