cant be sharpened out in the field at all?
Help me out here.
If this is the case then they are useless in terms or real survival situations.
If I need sandpaper/mouse/stropping rig to get an edge then I'm FUBAR.
 
Fred,

Convex is simple to sharpen in the field. If your blade is good and sharp already, it only needs stropping, which you can do on a leather belt, or some sandpaper over an altoids tin (siguy came up with a nice and easily transported unit.

Stropping invloves almost just the motion of "wiping off" your balde back and forth, away from the edge, leading with the spine. Don't use too much pressure, a few minutes with just the weight of the blade should do it.

Utter nonsense!

First, if the convex ground/edged blade is sharpened before you go out, you'll need to be out a very long time, or start chopping moose bones, before you need to sharpen it again.

Second, you can sharpen a convex ground knife on type of stone/grit/etc you could sharpen a bevel edged knife on. I've done it for decades. I've sharpened convex edges on Arkansas stones, diamond stones, river stones, and coffee cups. The mouse pad and wet.dry sandpaper just make it easier. But as long as you do it by hand, and try to keep a feel for where the edge is at, you'll be fine.

Now if you don't have clue one as to how to sharpen freehand, start learning now!

Finally, the whole stropping thing is not just a "convex" thing - it's a reality for any knife edge that if you strop it with a compound loaded piece of leather, yor edge will stay wonderfully sharp for much longer. Stropping the edge on your pants leg doesn't work quite as well, but works better than nothing.

If you feel the need for a minimalist convex sharpening kit to cover all eventualities, get a small, fine DMT stone, glue a piece of leather on the back, and crayon some black compound on it.

But personally, I just use the river stone and my pants leg! :thumbup:

I am horrible when it comes to sharpening. I have an EZE LAP dual side diamond sharpener, and can get a great edge with that and just stropping the blade on my denim pants or shorts (not liable :D). They might not be polished edges, but are useful, and are not wire edges.
 
Never mind............

I see "Grampa" got here first.:D

Just do what he says.:thumbup:
 
thanks everyone for the kind words but its actually rescueriley's idea. the one i keep showing is one he sent me.

Stropping is great to maintain the edge. It works good on pant legs if you wear canvas Carhartts like I do.

If more extensive sharpening needs to be done, I'd carry a DMT Diafold sharpener and do it freehand. Practice this first at home. Take a Sharpie and color the edge back maybe 1/4", and hold the knife still, moving the stone. Look at the marker, and get used to doing it such that you wipe all of the marker away with each stroke. Our hands naturally make curved motions, and people tend to convex edges whether they want to or not. The trick is to practice so you can follow the convex shape that's already therre.

According to some, a convex edge can be adequately maintained in the field by stropping it on your jeans (Claim made by Marbles Outdoors). They are supposed to be easier to maintain an edge on than any other grind.

You can even sharpen a convex grind on a (gasp) stone.
Its a knife...
don't over think it.
:D

Dude we are grown men, talking on the Internet, about knifes.
We are soooooo fare removed from any and/or all of not over thinking it, that there is no chance of us even thinking about looking back:D:D:D


As soon as I figure out how to make a qoute at the bottom of my page, that will be it :thumbup:

That is a non-problem anything that'll sharpen a knife will do. I doubt that bit about the jeans, at least my jeans have never been that filled with any abrasive...

i've taken to carrying a sanding belt and a strop. With a bit of patience you can do a lot with a strop, so I something rougher for the sanding belt. I used to carry a worn 320 grit, now I'm pretty happy with a nice fresh 600 grit belt.

But really, just stropping should do you fine, convex edges hold up really well.

Awe shucks...sometimes it helps to state the obvious.
:D

Stropping straight carbon on your jeans isn't about abrasives and grinding metal off the edge.
You are polishing the edge.
Polishing helps with a sharp knife that begins to drag a little.
Polishing also helps remove any oxidation/patina off the cutting edge.
Won't sharpen a dull knife, but will give a sharp knife that sat for a while a little more 'pop'.

I don't know about you, ...but after a couple of days in the field my jeans get pretty abrasive. :eek:
