For you experts out there (of which I am not one..), I need help sharpening my Busse knife (below). It is a Boss Jack convex blade, and was heavily used on a recent camping trip. Is there any special techniques or considerations for sharpening a convex blade?

I don't really have any knife sharpening gear yet, so please let me know what I should get to sharpen both this knife, as well as my SAR-3. I'm hoping I can pick up what I need from my local Gander Mountain store.

Also, if you have any ideas about how I can fix a slightly rolled edge in a small area (a few milimeters) near the tip of my blade, I would appreciate it. Someone mentioned using a screwdriver shaft to straiten it before sharpening, but I couldn't get it to budge..this is some strong steel!

Thanks very much in advance for any advice you can give!!

Sandpaper and a mousepad. Sandpaper and a stack of newsprint etc...

Go over to Youtube and search their videos for "sharpening convex edges".

I'd try steeling it before sharpening, it will help with getting that tip staightened away.
 
I suggest using a knife steel for the roll and the sandpaper/mousepad (or even a piece of that foam knife wrap that Busse now ships some knives in) method. Search 'mousepad', it should help to find a bunch of great threads on this. :thumbup:
 
Use a smooth steel or the spine of another knife to straighten out the roll before you start sharpening so you can put the steel back and then sharpen, rather than grinding away the metal.
 
First, steel the edge with a smooth piece of steel.

If you have a smooth round screw driver, that will work.

Start by trying to push the edge back into alignment.

Just spend some time and go easy. You should be able to get it mostly back where you want it.


Then Sandpaper over leather or mousepad backing. Then strop with a loaded strop with polishing compound.

Has anyone had experience with motor controllers? I have a Lenze for which the instruction are not too clear. The people I bought it from ,when I call them, do not answer specific but tell me how easy it is. Thanks,bullet1934

What?
 
Great, thanks for much for the replies. Mousepad and sandpaper....never would have guessed that, but it makes complete sense. Thanks for the video links - that will be great to get me started on this.

It might mention it in one of the videos, but what grit/type of sandpaper do you recommend?

Thanks again!
 
You will probably want a range of grits. Maybe 400/600/800/1200. Head to the local auto parts store, and pick up some 3M wet/dry sandpaper. Don't use the cheap stuff made for sanding wood.

Gonna need something around 200 for that tip...
 
I also like to finish it off with some 1500 or even 2000 grit and then a strop loaded with green compound to give it a razors edge. For even more get a buffing wheel or paper wheels on a cheap disc grinder and you can get it crazy sharp and you don't need a whole lot of practice with either one, just a little caution.

Of course ideally a belt grinder will get it air bleeding sharp but takes a little practice to get good and that's a whole other thread. I think getting proficient with sandpaper and mouse pad is the best place to start.
