Assuming you are wanting bush knives and not urban EDC's, OK here goes:
I use a number of rig combinations for bush depending on where and how long...
For a
walk in the woods I carry a folder---either my Case LSSP or Buck 110--virtually the same knife.. Sometimes I'll carry a J.Rozich dagger or smaller puukko on the belt instead, depending how "urban" the woods might be and whether I'll encounter the weekend Rambo crowd who might decide they covet my Rolex; or want me to squeal like a pig.
For
day trips or public campground stuff not involving an overnight, I'll belt carry a 4" leuku. Cheap folder in pocket optional.
OR maybe only my SAK.
For a
night or two camping in the woods I might carry my HEST II Woodsman with a sheath I modified to carry my Sebertool M-4 on the flap as well as carabiners and rings to carry any misc. small items like a fire steel, etc. Small leuku in my pack. Again, folder in pocket optional. I find in summer I can usually gather firewood without a bolo or khukuri being an absolute
necessity.
For an
extended trip in the woods I will likely carry my KaBar USMC gang-sheathed with EITHER a Buck Pak-Lite, my trusty BK-11 san mai or Eskabar, for smaller work. At this point my 16" bolo knife enters the picture (and stays there until an extreme winter trip might replace it with my khukuri for reasons below), usually mounted side-pack for overhead draw. Misc. heavy folder in pocket.
For
extended canoeing/kayaking trips involving overnights it's my Tekna Ocean Edge knife on my belt or waistband and a 4 or 6" leuku in my pack along with my bolo ---handle exposed for quick access in the watercraft. Folder optional if I have pockets, probably a RAT, Evispa, etc.---something I can lose.
Spring/summer extended trips into the wild I might carry my Old Timer large skinner from the '70's
OR the USMC on the belt with a puukko in my pack. In-pocket maybe a ZT 561 or original Masters Of Defense Point Man utility folder which is half serrated and can be handy.
Toward the more rugged stuff....
fall/winter extended trips in the wild...firewood being more critical in winter, I'll bring out my 7" leuku/ pukko single-sheath combination and HEST 2.0 folder in my pocket. Bolo in the pack. At this point my Brunton high-altitude lighter replaces the Zippo to ensure certain fire. I don't like to rely solely on a fire steel for winter conditions.
For
the roughest trips, say lengthy stay in the Sierra in fall/winter, It's my large leuku/pukko combo, Grayman or HEST folder in my pocket, 4" lueku in my pack. My khukuri may replace the bolo in the pack at this point for less weight on snow and ice; also not as much brush to chop in winter or above timberline; the khukuri is handier for chopping misc. firewood. The karda of my khukuri has been nicely replaced by a KaBar Acheron I keep super sharp for the small stuff in camp.
Forgot to mention, in all but Scenario 1 my SAK Officer will be stashed somewhere in my kit.
For winter excursions, fire being life or death I have either my Zippo or Brunton torch along. I'll also carry char cloth, a couple of Tampax (waterproof quick fire fodder and good for plugging gunshot wounds from drunk hunters) and maybe a magnesium bar for certain fire. Last ditch certain fire may even include the trusty 9-volt battery and wad of steel wool trick if the environment will be extremely winter-harsh---my favorite kind of camping.
Oh yeah, you wanted steels: D-2, S30V, O1, 420HC, 440-plain, 1095, 154CM, Hitachi white steel 2, CroVan, Niolox and Ford truck leaf-spring steel included in the above.
The wild card in all of this is the HEST II fixed. It can be thrown in and substituted for some of the main carries in all of the scenarios. Most versatile bush knife I own.
I guess the combinations can be endless and I have other knives I sometimes work into these rotations, but that's a good basic idea of how I tend to carry for bush. Hope it helps.
