TSPROF KO3 or KO4?

To test the edge, to move the knife to a microscope/magnifier, to safely store the knife if you need to pause in the sharpening, to strop backside if doing a single bevel knife, etc. These may not be things that come up all the time for everyone but I think it's a cool feature. I'm not sure if the K4 has a chisel adapter/holder but it would be especially nice to be able to deburr the back side of a chisel and repeatably return it to the jig.

I test every blade with a Bess tester. Rarely, but sometimes I examine the apex under a microscope. I would need a sharpener with a removable arm.
I am on the market for something like a KO4.

Most of the Kazak systems also have a removable clamp bar.

I'd love to have the K4! But my Edge Pro Professional uses a table instead of a clamp which offers the same benefit.

Fixed tables are inherently stiffer than rotating clamps, and have the edge in quality of end product. The two types have their strengths and limitations, which don't overlap much, so you need one of each to cover the gamut. Fixed tables need a flat surface to reference, so convex or hollow grinds can be a problem. Rotating clamps have so many connections in the system that they can't hold the blade as rigidly. The clamps themselves are a whole other topic.

The K4 is high quality, well made and a great system but in all honesty it does exactly the same job, with the same repeatability and accuracy as the K03. Either system would be a solid choice.

You need to examine the following: ability to adjust the height/sharpening angle inthree separate ways down to a level of 0.01mm - can’t do with k03. The stone thickness compensator is refined as is the position of the rotation knob to the back, much more accessible. You can also remove the clamp bar with knife attached. These are all K4 unique features not on k03

Is the K4 available in states yet or do you have to buy direct from TSPROF?

You can purchase it through tsprof asia, that's what I did, there is a link for it on the tsprof.us website, that redirects to the tsprof asia website. It's like 200 shipping and 80 ish import fee. When I spoke with the US customer service, they said they originally wanted to have it in by late november but were now targeting december/the holidays for it to be purchasable directly from the US website.

The process of getting it from asia was actually pretty crazy, I thought it would have been harder/more complex but DHL was pretty good about everything

A distinction without a difference i.e. the purported movement in the K4 system is virtually zero. The clamps don’t rotate, the arm they are bolted to is what rotates. In know of nothing that supports your claim regarding quality of the edge.
