Best Results for Sharpening the Off-Hand Side of the Blade?

Hi guys,

This is the sort of post that would make a much better video example, but I'll try to explain as best I can as I lack the proper video equipment to film myself sharpening.

I primarily use a double-sided DMT stone for my sharpening needs so those of you that have this or similar stones should be able to picture it fairly well.

I am left-handed, so when making passes over the stone with the knife in my left hand and my right hand lightly touching the back of the blade, I can get the right side of the edge from base to tip sharpened fairly well (if we assume right and left sides if you're viewing the knife in an upright position from the back). I hope I've explained it well enough so far.

However when I need to do the right side, although I can do it fairly well, it doesn't feel (in making passes) nearly as even or controlled. I try to hold the knife in my right hand for this but it doesn't give me as sure a grip or as great an amount of control. Therefore I simply turn the knife over but keep it in the left hand, while bringing the right hand over to the back of the blade. This also starts the pass at the side of the stone further away from me and moving in, rather than starting it on the side closest to me and going out. I hope you can follow me so far.

The results are still fair, certainly, but I'm never as sure that that side of the edge is getting as good a job done. What I'd like to know is if there is a way, when using stones freehand like this, to be more certain of a more even edge that gets just as good a sharpening as the "main hand" edge.

I'd prefer to find a better way to do this with my existing freehand stones rather than have to switch to some system (although I know good ones exist.)

But the DMT stuff has been great so far and it's been a joy learning on it. I just need better control on that off-hand side. Any thoughts and help is much appreciated. Thanks guys.

Yes, a video would be very helpful here but I think I know what you are referring to. I have always had problems with using my dominant hand only to hold the knife in regards to grind paettern and angle. It seems my forhand angle is always more acute than my backhand angle. I help myself in a way that I use my pinky as a gauge for the height of the spine and that of course helped a lot. I practice sharpening using both hands alternating with the spine facing me too.
 
Thanks mate.

Practicing with my off-hand wouldn't hurt either... plenty of cheaper knives to work on with that.

A very quick way to see if the angle is matching up, between hands, is to color the lower 1/3 or so of each side with a marker (Sharpie). I've also noticed a tendency of mine to be a little more acute with one side than the other. The marker on the blade will make it more obvious (ink will come off higher on the blade, on the more acute side), and you can tune your hold and/or stroke to even it out. Can also pay attention to the direction of the grind lines this way, as they'll stand out more clearly against the backdrop of the darker ink.

I'd also suggest practicing with both hands, working to 'mirror' the hold and stroke to your dominant hand. It feels strange for a while, but your hands will still 'learn' the process, even when it seems like it's still awkward. So long as you keep working at it, you'll eventually notice that your 'off' hand is picking it up, and it'll feel more automatic.

Great advice as usual David, thanks! I am sure this will improve with some time and practice, and the above video has been very helpful. I find the back and forth motions used to be working much better for me that the single forward strokes I was using. Seems to be steadier.
 
I prefer alternating hands when sharpening on bench stones. I'm actually getting a more consistent angle using my weak hand. I think it's because I tend to push the knife with my strong hand instead of just holding the angle with the hand gripping the handle and pushing with the other hand.
