Continous vs interrupted diamond hones

Just looking for your thoughts here. I recently got the KME system and I do love it. I do however seem to get better results when using the interrupted diamond hones from my DMT Aligner than the continuous gold series diamond hones from KME. Does anyone have any thoughts on this. At the moment I'm using a method to mount the longer DMT hones suggested by someone else on this forum but I think I have a slightly better way, I'll post pics when I get the piece that I need, that is if it works.

Just wondering on your thoughts on these two style hones?
 
I prefer my duo sharps to my diasharps, so in some instances I prefer the interrupted surface.

I have had issues with some of the individual benchstone interrupted hones being out of flat immediately surrounding the holes as if the punch distorted the surface, but have seen no trace of this on the duosharps. An not a fan of doing tips and sharp corners on them but is not all that difficult with a bit of familiarity.

It also seems the interrupted surface hones have a much shorter break in period - they come "cleaner" from the factory.

I have zero experience with the KME hones.
 
I have both types of diamond bench stones (continuous and interrupted) and see no basic difference in performance. I only use them for major resharpening or reprofiling. I rarely need to do either as I keep my user knives sharp with fine Arkansas or ceramic bench stones.

Thanks for the info guys. I agree the duosharp seem to have a shorter break in period. I continue to use both, they both work well so it's all probably my imagination.
 
The only duosharp I have is the double sided dia fold for hunt'h/fish'h and fast touch ups. Works very well. My bench stones are all 8" diasharp plates I like them better for large stones personally. main reason is that I often reprofile and sharpen small pointy knives like B&T's, parers etc that have thin sharp tips..Ive caught the point of them several times in the duo sharps holes..My fault too, I know..I just like the big 8" heavy plates..
I would like to have a couple of the 10" duo sharp plates for plane irons and chisels..They shine with those..
 
There's been discussion here of DMT continuous versus interrupted plates. I don't know how to compare KME continuous versus DMT interrupted.

In the DMT discussions, different people have said opposite things: Some saying that interrupted worked better/faster. Others saying continuous worked better/faster. DMT themselves claim that the interrupted work better/faster. I haven't used both, so I can't really say. I've always thought it was odd that DMT says what they say. <shrug>

Keeping them both clean is important. Also, using low enough pressure that you don't strip off the diamond coating is rather important. Fewer diamonds on the plate certainly means less grinding power.

Depending on who manufactured the hones, and with what process, there are often noticeable differences in hones otherwise rated similarly or identically. DMT famously uses monocrystalline diamond on their hones, whereas many (most) others seem to use polycrystalline diamond. Even at the same rated grit size, the mono diamond will leave a finer & more consistent finish (this is what DMT is known for), whereas the poly has a reputation for faster grinding, but leaving a somewhat coarser finish (EZE-Lap hones perform this way). Less-expensive diamond hones might be less dense in diamond coverage on the hones and/or less tightly controlled in grit size and uniformity of grit shape; any of these differences will affect how they perform as compared to other brands.

If only comparing DMT's different lines to each other (DMT's continuous 'Dia-Sharp' hones vs DMT's interrupted surface hones), they all use the same monocrystalline diamond and can both perform essentially the same in terms of finish left. The interrupted surface hones can leave a somewhat irregular 'wavy' finish if the pressure used is too heavy. If used with an appropriately light touch, however, I've not seen significant differences in either, in terms of grinding speed or finish.

Just personal preference, I go with DiaSharps (continuous surface). The biggest reason is sharpening a fine tip. The divots in the DuoSharp (interrupted surface) can grab a tip. Not a super big deal....you can use (and should be using already) light pressure.

Not too sure about the claim that interrupted is faster. I really don't see how that could be possible. You essentially have half (guessing) the amount of diamonds, correct? Not so sure about the whole "swarf falls into the holes" concept either. I guess if you're using it dry, then the holes might work for that. But I always use soapy water to help swarf off the swarf!

Now they have a THIRD line of diamond hones with some sort of weird coating on them.
