How to open
Holding the Pebble in your palm, with the logo facing you, push upwards with your thumb on the grove.
Assembling the chopsticks
The chopsticks come in two pieces that screw together. The metal tips store away in a hole in the top the handle. The easiest way to assemble is to first pull out one handle from the case, then screw that handle into the top of the tip that's still inside the other handle. Then remove the handle still in the case, and screw that handle into the tip that's in the first handle.
Tightening the cutlery
The knife, fork and spoon fold to store. The hinge that allows the fold should arrive at the correct tightness, but if it needs adjusting or comes loose over time, simply take a 2mm allen key (also known as a hex), and tighten by turning clockwise.
Using the Flex-Clip
The clip for the Pebble has been designed to have an end that is easy to remove the Pebble from, with only a small amount of play before the Pebble comes off, and another end, with more play, with is harder to take the Pebble off of. The wide, flat end is the end that's harder to remove the Pebble, and should face down if you want to keep it more secure, say if it's clipped to your belt loop or bag. The curved end is easier to remove the Pebble, so have that end facing down if you are using the supplied lanyard around your neck.
