Workshap Riser System,Attachment for Ken Onion Blade Grinder,3-Piece Adapter Riser Set for Work Sharp Ken Onion Elite Knife Sharpening System

I have neglected purchasing the blade sharpening attachment for my Work Sharp Ken Onion knife sharpener up until now because I didn't like the idea of having to guess at the correct angle for sharpening. I never understood why Work Sharp designed the attachment the way they did instead of simply providing a built-in rest for the knife. As soon as I saw this attachment, I bought it and the blade sharpener at the same time. It does an excellent job of supporting the knife and providing the correct angle. It is reasonably sturdy and is certainly more competitively priced than other aftermarket rests that I have seen. As others have noted, the bed attachment is way too loose and will slide right into your grinding belt. One reviewer suggested drilling a hole through the bed and attaching it with a screw and wingnut. I don't like this idea because you do need to be able to slide the bed in and out, depending on the angle that you are grinding at. I simply took a small piece of blue painters' tape and wrapped it around the bottom of the bed to hold it in place. It works quite well and is easily removed to reposition the bed. If the designer is reading this review, a simple series of click-stops molded into the bed could have solved the entire problem. I would never have purchased the blade attachment for my knife sharpener if I hadn't seen this little gadget. It is well worth the price.

As others have mentioned, the fit is loose but easily remedied with some masking tape in a few key areas. For the price, it's very much worth it. I don't have the time, nor want to spend the money on a 3D printer to try to make my own......

junk cheep plastic base cracked on firt use very loose fit wobbles all over

I like it. I am not the sharpest Tool in the Shed , But maybe this will help ! Just look at the Pic and slide it on.

Fits well (did need a little tape inside fit, now tight). Works perfectly. Hard to believe work sharp did not include a riser.
