I don't do a keychain, and anything meant to go on keys ends up looked in pocket if I carry it at all.
These are all tools of some form meant to go on a keychain, and as you can see only one has a key on it, the COLE 4-way that has my toolbox key on it.
Everything else ( if it's something I ever carry or use ) goes loose in pocket.
The leatherman Micra and my current favorite the squirt PS4 get their " lanyard hole " folded away and are dropped in my pocket along with my actual knife.
Same goes for the Victorinox classic which is the most popular keychain knife / tool ever.
My grandfather carried that yellow one loose in pocket as his only knife, it's not enough knife for my taste but it's blade has it's place and the tools are always handy.
The Christy knife was my only pocket knife for the month as has been the Gerber LST and the tow Bucks at times.
The Dasco prybar and little stubby bit driver clip to my work bag, the mini tape measure in my shirt pocket with my leather key fold and Fisher stowaway pen.
