What's your pick. Going to buy one in the next couple days really leaning tord the Falkniven DC521 but want to hear your thoughts. I have heard that the diamond side of the falkniven starts falling off has anyone had this problem?
 
At least some diamond comes off all diamond hones, as part of the normal break-in for them. Wouldn't surprise me if some of the 'reports' of diamond coming off are coming from users applying too-heavy pressure, which will do damage on any of them. That complaint seems universal among first-time users of diamond hones in general (I had to re-teach myself how to use them properly). BUT, if there is a genuine quality issue with the Fallkniven hone, that's what factory warranties are for.

I have a Fallkniven DC4, and haven't seen anything to indicate a problem with the diamond on it. I've heard/read here on BF of some inconsistent finish issues on the ceramic side of some of their hones, but even that seems to be hit or miss, depending on who you ask. I don't have any complaints about mine.

AND, I seem to recall just ONE mention here on the forum, of a Fallkniven hone that separated halves (steel plate w/diamond side came loose from the ceramic side; apparently an epoxy issue). But I've only heard of that issue the one time.

At any rate, I wouldn't put too much stock in isolated reports of failures. These things happen to any manufacturer, but sometimes the reported issues become overblown. The failures always get more public attention, and the successes usually go happily unreported.

I have used a full set of DMT diasharps for several years now and have no complaints. I probably put two lifetimes of use on them and they have never given me anything but the best results. They are not for every steel or every knife but very hard to beat IMO.
 
Low alloy steels or basic carbon steels are better done on a less aggressive abrasive, diamonds do best on steels with wear resistance. They tend to gouge a steel without enough wear resistance.

Also grind types like the scandi grind are just not for a diamond plate, the mix of steel and large grinding surface are better done on other stone types.
 
I have a Fallkniven DC4, which I've actually never used, so I can't comment on the diamonds falling out or the quality of the edge. I can comment on the diamond size: I have looked at it very carefully under magnification and the diamonds are approximately the same size and distribution as DMT Coarse.
 
I had the actual plate that the diamonds are bonded to separate from the ceramic stone of the dc4. I epoxied it back together. Been fine ever since.

Thanks!
Even with minimal pressure? Am second guessing my portable sharpening setup here ..
