It depends on your definition of workhorse...
The blades I abuse. These are used to chop roots, strip wire, cut wire, cut against metal, cut sandpaper, pry with, everything you want to do with a knife but aren't supposed to

They are cheap, and I don't care about their longevity so I don't hesitate to regrind them after I put some big dings in the edge. The long steak knife used to be about 1/4" wider, and had alot more belly.
As for my blades that I actually like

They have all served as EDC for a time, some of them for quite a long time (relatively speaking for this crowd

) The one on my belt now is my woodjewel, which I actually forgot to put in the picture. I trust all of my EDC blades to cut for me, and cut very well. I use them well, but don't abuse them.
The one on the far left is one that I'm just finishing up, it will go on my belt next. It's just waiting for the sheath leather to come in the mail, and then it will be in pants and on my belt faster than you can say shazam. I have some in progress shots of it, I'll do a longer writeup once it's all together.
