Hey everyone, first post here but been lurking a while. Had a question about sharpening my knives (newbie here though Im familiar with the basics... i think). My friend was getting rid of some junk he didnt want anymore and I said I'd take his DMT aligner tool along with all his stones (I have XXC, XC, C, F, XF, and XXF) so I figured i should be set in the equipment department. I also have an old smiths trihone (with aluminum oxide/medium/fine stones). Ive always been able to sharpen knives ok but never shave sharp or anything like that. I do have a jewelers loupe since I enjoy fixing watches, but dont know what to look for when sharpening because all I see are the scratch patterns. Anyway..

I was talking to my friend and he said that to get the most out of this aligner, i should reprofile the knife with the XXC to make sure the guided system will actually be hitting the bevel, because the factory bevel might be at a different angle than the lowest setting on the DMG Aligner (in fact im sure it is). It sounds like a good idea. But i was worried about taking too much metal off. Do these DMT stones raise burrs, because I was using the XXC on my Kershaw NeedsWork with Sandvik 14C28N steel, and i was unable to get a burr raised. Should I keep grinding until I get a burr or am i just wasting time/metal? The XXC seems plenty coarse so im sure its not worn out or anything, it looks barely used. And since im going to be progressing through all these stones... another question.

After I raise a burr on both sides, assuming i can with the XXC, do I then start the alternating pattern, going through all the grits, or do I keep working both sides separately, getting a burr again on both sides with all the grits. If that makes sense :confused:

Any help would be appreciated.
 
Decided to try a different knife, my benchmade mini griptillian (154CM). Worked at it a bit more, and with more pressure, and am actually getting a burr now on one side. I guess the XXC stones aren't as coarse as I thought they'd be and need a bit of pressure. Still a bit confused on what to do after I get a burr on both sides though.
 
Start with the coarse hone, and by the time you establish the bevel you want, and there should be a burr. Then work progressively up through the finer hones until you get the edge you want. I wouldn't worry about taking off too much metal. I find that once the bevel is created it stays that way for a long, long time, provided you keep 'em sharp.
 
I read that once you raise a burr on one side, you flip it over and get the burr on the other side. After you get the burr on the other side, you do alternating strokes only. Now since Im definitely getting a burr with the XXC stone, when I move on to the XC (and C, F, EF, EEF) do I only do alternating strokes with those stones? Or is this just misinformation?

I'd skip the XC and go to C. You'd be wasting alot of metal forming burs on every stone in order from XXC. From C you could go F EF EEF.
 
Ok. But do I alternate sides now or can i work one side at a time? I've gotten a good burr on both sides now with the XXC.

Very Very very light pressure, let the hones do the work or you will end up ripping the diamonds out of the substrate and ruining your hones.

I like working one one side at a time. Honestly I really dont think it matters.
 
Cool. Thanks for the advice everyone, huge improvement. Didnt start alternating till towards the end with the EF, EEF stones when i wanted the burr gone. Quite a nice knife now. Doesnt shave effortlessly but still plenty sharp. havent stropped it yet either.
 
If you have the money I would suggest a spyderco UF ceramic stone. When I freehand its the last stone I use before stropping.
