I gave up entirely on my DM CG, not having any power tools it would have taken too much time and effort to modify.

Yes, without a belt it took me at least 45 minutes to convex the S6. But I enjoy that kind of thing so its not so much "work" as it is "hobby". Someday I'll get a belt sander and be dangerous.<img src="/ubbthreads/images/graemlins/grin.gif" alt="" /> The total cost to convex that S6 and Busse HS was under $10, not including the price of my strop bat that I already had ($35) and I can do several more knives with those 4 pieces of sandpaper and a mouse pad.

Ever since learning how to convex by the mouse pad/sandpaper method, I have convexed all of my V-grind knives. The person who showed me how to do it on another forum was a maker named Garrett Schmidt, a knifemaker, who came up with a clever set of diagrams to show how its done in a very intuitive way. In Garrett's words, "the main thin you are trying to do when converting a V-grind to a convex, is to knock off the bevel shoulders'. Taking this thought a bit further, you can, but do not have to, actually touch your edge. By knocking the shoulders of the V off at the bevel you are decreasing drag through the slice and increasing cutting performance by reducing friction at the edge/bevel junction.

Now perhaps this doesn't make this a true convex conversion, but rather a hybrid which seems to optimize the advantages of both edge types. Personally, I feel a little the way Doc does. I enjoy convex, but I hate the effort it takes to strop a blade to razor sharpness. Mostly what I do is convert the V-grind to convex by mousepad/sandpaper through to 2000 grit. Then instead of stropping, I simply put a micro-bevel on it with the sharpmaker. The micro-bevel takes about 30 s to produce and I think yields as good as an edge as a true convex one establed by stropping. A final point is that even if you have a fully convexed blade, there is nothing stopping you from using a stone or a ceramic rod in the field to put a micro-bevel on. It won't take any more effort to field sharpen your blade like this than any V-grind under the caveat that your micro-bevel is performed at a more obtuse angle than the final edge of the blade. Also, in contrast to the purists - you aren't suddenly destroying your convex grind by putting a 0.5 mm microbevel at the very edge. If you want to re-convex it, take a about 30 swipes per side on 1000 grit then 2000 grit with the mousepad/sandpaper and proceed to a strop. Its as easy as that.

Batonning - heck doc - we probably had our share of debates on those other forums. If you know me - I baton 20x more than pre-pubescent parade girl ever would dream of. I've batoned the hell out of 0.095" thick knives without problems. The way I usually qualify things is that there is a continuum to how you baton. You start the split and you can usually feel when there is too much resistance to proceed. You don't have to finish a baton if you feel it is adding to much stress. If I were in a survival situation, I wouldn't hesitate to baton. But that doesn't mean I wouldn't use common sense while performing this activity or really on my personal experience with the knife I'm using.

One reason I baton often with my knives is so that I get to know how they perform so I know how they will perform when I call upon them. Better to have a blade snap in my backyard than at camp. If it happened in the wilderness, I'd probably have to go to the trouble of reaching using my weak side hand to draw on my secondary belt knife <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />

Finally, I'll admit. I buy scrapyards to beat the piss out of them. I don't find them particularly pretty knives, even when they are brand spanking new. They are about as pretty as Mike Tyson but also as tough. For me, the whole point of buying Scrapyard is so that I can smirk at the words 'abuse'. 'Abuse' its not even in the vocabulary of Scrapyard!

Well said, though I disagree with the statement that Scrap Yard knives aren't pretty.

There is a certain beauty in a purpose built toughness. If a tool can perform its task to perfection, with no wasted effort, and stand up to use and abuse, there is a beauty in that to me....but then again, I think A-10's and F4 Phantoms are gorgeous too.... <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" />

Yep - when I'm batoning in the back yard, or car camping, I will INTENTIONALLY choose the worst logs to baton - I find nasty, big, ugly knots, seasoned hardwoods, and twisted and gnarled abominations that look like they couldn't possibly be a product of nature. If I can baton a knife through those with no problems, then I know I can baton it through woods that are chosen more judiciously in the field.

This M9LE took a little bend in a ridiculously hard bit of birch that happened to have a fork at the base of the log. It sprung back to true as soon as the log was split, no worse for the wear, and I've got a pretty good idea that it can handle more than I would throw at it in the woods.

Mustard Man - that rat bending like that and springing to true is very cool!
