"This is a great little (tiny) pocket knife. If you work in an office environment this knife won't scare anyone when you bring it out to open boxes, letters, or cut loose threads off of your clothing. Put it on your keyring or add a small lanyard to it and you are good to go. Be careful... this little knife is sharp!"
"This is what I use for my key ring. Add a small knife, screw drivers, flashlight, storage container, and of course keys to the s-biners. I use 1 s-biner per item on my key ring. The s-biners are great for removing the items (like your knife) from the key ring and using it and putting it back on when you are done. It's like having a mini toolbox on your key ring."
