So this product is not on the CKTG website, however this might shed some much needed light on this product. (the bob kramer video is very popular and I'm sure many people want this kit when they first start out)
I bought this kit mainly for the sink bridge and resale of the stones to to friends who want to get into sharpening. It was on sale so I pulled the trigger about two months ago.
The kit includes:
A sink bridge
400, 1k, 5k chosera ceramic stones (like shaptons)
The sink bridge is a nice step up from my old setup (in sink cutting board with universal stone holder)
It holds any size of stone you could get your hands on and it can change stones quickly as well. Holds them nice and secure.
If you don't have a perfectly square sink this product might not fit all that well. I had a little bit of trouble at first.
The sink bridge can also be collapsed and used as a counter mounted option with tacky feet to help keep it in place. It doesn't work all that well and I would prefer the universal stone holder with greater surface area contact with the counter. This being said on small stones sometimes you can get knuckle drag with the universal stone holder. Not with this product as it is about twice as tall.
The stones look identical to shaptons in every way except for the fact they are the size of the shapton extra thick stones. They differ in shade, starting at 400 it's black and going all the way to pure white at 10K.
These stones cut fast, just like shaptons and they don't dish quickly. With use, I believe shapton actually made these stones for chosera. They operate and feel exactly the same. This is a good thing as shaptons perform very well.
Overall I think it's a good kit to get started, but the 1k-5k jump is a little too large for me. Not sure how this stacks up in price to the shapton combo kit mark sells but if you wanted a one and done this isn't a bad idea. You just pay a lot for the brand name
I believe they sell the sink bridge separately. If you are looking for a decent sink bridge you could give this one a go. I like it and it works well for myself.
