Knife sharpening

I bought one of these

VSharp on Teh Smilez

at the BIG gun show in Tulsa.  I've seen the guy selling them there for, I dunno, more than a decade and I decided that if he was there, I'd buy one, so I did.  I think they are actually cheaper on Teh Smilez.  It does a great job on knives that aren't sharp, using the 300 grit diamonds.  I bought an extra set of diamonds in 1000 grit.  That works well for knives that are already fairly sharp.  Then I touch them up slightly with one of these.

that I bought at Sturgis in '16.  I bought a couple more to leave around.  They are only $15 shipped, and they take paypal.

I was hoping that CWH was back...Has anybody heard from him?

In reply to Woody :

SVRex mentioned in another thread he’d talked to Chuck on the phone recently & as far as he could tell things seemed fine. 

Talked to CWH’s wife today. He’s doing fine, but has had some computer problems. 

I told him to get his butt back online, that folks were missing him!

In reply to SVreX :

Awesome! 

So what's the solution for something like a serrated bread knife?
