Worksharp Precision Adjust. I hate it! 

Yep. I have the same sharpener. Gave up on it after all the modifications I made to it so that it would actually work. The first of many problems, is it’s too light. So you have to hold the base down but soon realize that you need that other hand to hold the adjustment in position because it drifts out on the sloppy worm screw and plastic threads. So I screwed the base down to a board and clamped it down to my workbench. (I’m stubborn so I eventually solved every problem) The angle adjustment doesn’t lock in place on either guide, so I made a couple plastic shims and would tap them into the space between the guides and the riser rods. Now it’s locked. The next problem is easily seen in your video. The blade clamp has just enough flex to throw off the angle as you can see happening while you sharpened/dulled your knife. So I cut a block of wood that fit between the blade clamp and the base to keep it from flexing downward as you put pressure on it. Then I picked up a digital angle finder that cost twice as much as the sharpener itself, because I knew the angle markings on the machine were wrong. I ignored the markings and went with the angle finder. Now the worksharp was actually working well. I made perfect edges on all my knives! But if you thought using this sharpener was a pain before, try it with all the modifications that have to be removed to flip the knife over or change angles? Now it’s a project. And by the time I was happy with the results, the stones were worn out. So I gave up and spent the $400 bucks for a real sharpener. The TS PROF KADET PRO, is sort of the same style sharpener but it’s all metal, heavy, precise, and everything locks in place with zero movement. And you can sharpen blades as long as a machete or as small as a tiny pen knife. This is a precision machine where the worksharp is a toy. It’s expensive but well worth it if you want a perfect edge without all the screwing around. Thanks for the video, I do feel your pain brother. 🤙🏼

I bought one last year and it was faulty, one of the magnets that hold the clamp was set too deep so it wouldn't hold the clamp in place. The replacement was better, but there is too much play in everything due to them using plastic. I can't fit my Cold steel Master hunter in it as it has too much movement in the clamp. It seems ok for folding knives with blades at 4 inches or less, but the clamp still needs supporting during use.

Not a fun process at all and you see the start/stop of each stroke on your blade. Plus these are only really usable on small knives. Of course I'm partial to using a 2x72 and a rail sharpening system like the Perfect Blade attachment. 😜
