I have this at home and it is my favorite way to sharpen. Just keep in mind that this is not a guided system. It takes learning, finesse, and a steady hand. It produces an unquestionably top notch edge in the right hands. In the wrong hands, it will absolutely destroy the look/tip your knife in the blink of an eye. I don't think is has an equal on the market. Plan to start with knives you don't mind damaging. Guided systems all have their own limitations as do stones. Not all knives are designed with sharpening in mind. This compensates for the deficiencies in a guided system. I have sharpened axes, swords, machetes, lawn mower blades, and several hundred knives with the one I have at home. I've even reshaped blades from saber grind to full convex. Belt variety is limited, but most of what you could want is available, not always through work sharp. The deflection of the belt makes the sharpener inappropriate for a true scandi grind but is capable of so called scandivex.

You also need to be wary of edge and tip heating, especially on thin knives. Since you operate the sharpener with two hands on the knife, there is no reason not to notice any heat. Rated duty cycle is one hour on, one hour off.

It's too bad they don't sell the Ken Onion compatible "motor" separate from the Ken Onion sharpening guide. I feel like I'd never use the sharpening guide if I had this attachment.
I have this, and honestly I haven't used it. But I have it when I need to sharpen my 11 degree angle stuff. I just hardly use my expensive stuff much, so haven't dulled them enough for them to need a sharpening. I do have a push pull stone kit too, and think this with a leather strop will be a better option.

That's a common observation with Work Sharp. Some of their bare systems need some not insubstantial additional purchase for it to realize its potential such that the stock functionality becomes unnecessary or almost unnecessary. You could say the attachment provides the more zen sharpening experience while the stock guide is for your more "git 'er dun" type of tasks.

I'm lost on what this does differently than what comes with the worksharp. Does it just create a different technique using the same motor?

I've got a spyderco sharpmaker but to be honest can never really get shaving sharp with the thing like I expected.

Well, I didn't know I needed this until now. I got the Ken Onion sharpener a while ago on a good deal, why not this one too. I got the 40% off with Discover CB. So knocked it down to $36. Also got the $10 small business credit on prime day for the purchase.

As others pointed out, I only use this grinder attachment to sharpen my knives. I find the guided system that came with the Ken Onion motor very annoying and now just sits in the box. Once you know how to use this it's infinitely faster and easier. I also bought the stropping kit but honestly, unless you want to shave with your knives, that is overkill.

This is just an attachment to the Worksharp Ken Onion Edition. You can buy the sharpener and this attachment in a bundle but you obviously won't be getting the deal price. As for the attachment itself, it offers more versatility for custom angles and edges. The stock attachment is very limited—hard to sharpen items such as lawnmower blades, axes, and specialty blades.

From others on product Q&A page:

"This attachment is MUCH better than the stock attachment, especially if you are sharpening a knife such as a Chef's knife. The stock attachment tends to grind away more material at the first part when you start the pass. On a chef's knife, this creates a concave section at the bolster which is a very important section on a chef's knife. if you're trying to dice things like mint, onions, basil, etc., this raised area will not cut and on a chef's knife, that is a real pain in the butt. This attachment has worked well for me sharpening chef's knifes and any other blade."

"This Blade Grinding Attachment have many good attributes: have the ability of complete angle customization and the ability of adjusting an edge profile. This Attachment don't just a sharpener, but a very good blade grinder, especially for the convex edge. I like it."

I ended up going with the Work Sharp WSSAKO81112 Blade Grinder Attachment with Assorted Belt Kit for $75.43. It came with the 5 belts as well, and it'll be nice to have the extras on hand.

Can't wait to sharpen my mower blades with this attachment. I did it with the standard setup, and it was a bit awkward at best.

Thanks OP!

I would guess that they got unexpectedly bombarded with orders for this. I selected same day shipping because they offered it, but amazon couldn't deliver. I bought the complete kit and they delivered the main unit and the belts, but not this attachment. I assume they flew some in overnight because I'm getting a very rare morning delivery from Amazon today.

They should have kept the promotions separate; 10% back on the amazon cc or the $20 discount on the attachment, not both. Both promos netted a ~33 percent discount on the attachment and nobody even remotely interested is going to pass on that, including people (myself included) looking to pick up base unit as well, especially given the with the 10% back on the main unit too, that gets you to about 20 percent off the entire system.
