Please provide your criteria for "Heavy Duty", without said criteria it will be difficult to identify the correct tool for your task.
 
Which SOG?

Are you looking for fixed blade? Folder? How big of a keychain? Tasks? Budget?

My current keychain knife is a Swiss Army Mini Champ that is at least 17 years old and I haven't broken it yet.
 
Cold Steel Micro Recon . :cool::thumbsup::thumbsup:

Has a genuine Tri-ad lock , just like the big ones . So not going to close on your fingers .

Good grip, especially if you use your keychain as a fob for the knife .

About as "heavy duty" as can expect for the size and wt.

~$20 , come in various blade shapes . Mine is spear point . But Tanto and clip are available . IIRC .

A Victorinox Cadet is as large and “heavy duty” as I want to go with a knife on my key ring.

Even then, I don’t want to have it on my keys unless absolutely necessary. I hate keychain knives.

My wife, on the other hand, loves all sort of junk on her keys. Including a micro SAK of some kind.

Henry, you've hit on a great answer. I don't particularly like the micra, but its a very rugged little beast, has a thin chisel grind blade that cuts like the dickens, and has some screw driver tools that will do a good amount of light prying if needed, and scissors that will cut almost as wide a variety of stuff as EMT shears. And if you fold it up with the blade out, its like a hybrid cross of a locking blade and balisong; no way for it to fold up and cut you if you're doing something outrageous with it.

You just may be onto something Henry.:thumbsup:
 
Maybe one of the CRKT Mininalists? They're dinky, and plenty strong for a keychain.
 
Spyderco ladybug is one of best,i have older version in aus.6,its excellent,reground it to zero edge...cuts very well...easy to resharpen and be open one handed...the new versions are too expensive...
 
I've had a SOG Micron on my keychain for many years. I guess I'll have to admit I've never tried batoning with it, so I can't comment on how heavy duty it is...

I once went through a security checkpoint at a state building with a Victorinox Classic in my pocket. They made me toss the Vic, but handed me back my keys with the SOG Micron on them. I made sure to point that out to them when I left the building. And I made sure I was holding my pencil in a reverse hammer grip and in a menacing manner at the time. ;) (Just kidding about the pencil!)

Vehicle keys I always keep separate in case of loss or theft. I have a few motorcycles so I don't want the other keys ejecting along the road.

The truck uses a fob that just needs to be in my pocket but I still keep that one separate too.
