Stick this precision screwdriver in your tool roll. It saves the day when you need to fix your glasses, phone, or camera on the trail. It includes 5 different mini screw heads, including Torx and Philip's heads. It is lightweight aluminum and compact.
You don't expect a small, precision screwdriver in a motorcycle tool roll, but I will not ride without them since I wear glasses. One time, while taking a break riding in the Pyrenees, I was wiping my glasses clean when I noticed the screw retaining one of the lenses had almost come out of the frame. Luckily, I had one of these screwdrivers with me.
Without it, I would have never been able to screw it back in because the screws are tiny. I do carry a spare set of old glasses with an older prescription, but those are just for emergencies so I can see where I'm riding on my way to the optician :-)
Up to 5 heads fit inside the screwdriver housing, and it weighs about 35 grams. The knob on top of the screwdriver has a bearing in it and rotates without friction, making it easy to remove screws with one hand.
