I have a canadian special that I was out camping with, after I got home I realized I had two small wavers-kinks near each-other on the blade. Not vertical like chips in the blade, but its horizontal, so the metal is still there just needs to be restraightend.
Having a convex edge knife is new to me.
I have a strop and the bark river compound
but havent had the need to use it until now.
I also have a mousepad and could buy whatever sandpaper it takes to fix it.

I also wondered about using a straightening steel for kitchen knives???

So Im a complete newbie on this any help would be much appreciated.
oh and I also have a spyderco sharpener, but probably not the right tool for the job.

Thanks.
 
imo straightening is the solution. if you try to abrade it you'll end up with serrations as the abrasive will remove everything that's not aligned with the rest of the blade.

try gently straightening with stropping strokes on a smooth steel.
 
Same thing happened to my BRK Golok... same thing happens to a lot of BRK knives. It's from having such a thin edge. But I'm surprised it happened to your Canadian Special, as I thought it was mostly a problem with larger and heavier knives that get pounded on, like the Golok and Bravo 1.

About fixing it... forget the strop. I've been stropping mine for about six months now with diamond paste and the only thing that's happened is that it's now a shiny damaged edge. Sandpaper and mousepad will work if you start with a coarse enough grit (like 180, maybe coarser) to take some steel off and bring the edge down past the damaged area. But I'm affraid you will loose a millimeter or two from the edge (and thus the original geometry), as that kind of deformation can't simply be straightened with a steel... the steel (A2 @ 58rc) is too hard and too thick at that point -- if I'm understanding the damage correctly. A steel is only for straightening the very thinnest point of the edge, its apex where the two planes meet and terminate. One bonus to grinding past the damage is that it'll almost certainly never happen again b/c the edge will be thicker and more robust. A slack belt grinder is also great for fixing this kind of problem, if you know what you're doing with it.

Good luck, and, if you can, maybe post some pics of the damaged edge.
 
Send it back to Barkt River for a Spa treatment thats what the life time warranty is for, get it back good as new
 
Thanks for the all the replys, want to fix it myself. but I dont feel like I have the experience yet to do it myself. would rather practice on other knives first than put my canadian special in worse condition... I'll put my trust on the bark river team to bring it back to life. thanks again.
 
Please let us know how it all turns out. I bought a used Highland Special in the sales forum and it has the small ripple, probably similar to your's. The knife is still shaving sharp so it's not a high priority, but I'd like to know what BRKT is able to do about it. Anyway, good luck.
