I did a long and detailed review of the Angle Set on a knife forum, and for the sake of brevity will post just my "Conclusion" section here. If you're up for a journey into the weeds, you can read the full review here: https://www.bladeforums.com/threads/the-new-work-sharp-“angle-set”-sharpener-review-sharpmaker-comparison.1693208/

Conclusion
My final assessment is that the Angle Set is a very innovative, well built, and versatile “in between” sharpener—and a terrific bargain to boot. What I mean by “in between” is that, even with the heavy diamond emphasis, it will of course never be as fast and effective for bevel setting or edge repairs as something like the Work Sharp Ken Onion powered system. And on the other end of the spectrum, as presently constituted, it can’t beat the Sharpmaker for touch ups and edge refinement due to the lack of a medium grit ceramic.
But what it can do is be a heckuva all round kit to take on camping, hunting, or fishing trips, or when you go visit friends and family who would appreciate a quick “in home” sharpening of their kitchen knives. The diamonds will give you the ability to modestly rehab any neglected and abused blades, and if you end up giving them a toothy but decently sharp edge, non-knife folks will likely be happy campers.
In addition, thanks to the easy store-ability and bargain price, the Angle Set would be a very handy item to have in your kitchen, fast and easy to grab and use either when the ceramic is sufficient or if you don’t mind a little diamond toothiness.
I haven’t had the Angle Set very long, and it may be that as I use it and get to know it better, my thoughts will evolve. But I’ve already seen enough to know it’s another innovative and high quality product from Work Sharp, and I bet they sell a boatload of them.
Finally, I think I should answer this question: Would I buy the Angle Set? While it doesn’t replace the Sharpmaker for my personal needs, it’s a different critter with its own advantages. Moreover, the Angle Set is so innovative, so well made, so versatile, and such a screaming bargain, that I wouldn’t be able to resist adding it to my sharpening arsenal. So, in a word, yes!
