I have been looking at all the different sections on this forum and I have back to the maintenance and tinkering section a lot and I have been watching the forums for about 8 months now and this section kind of makes me laugh because I don't think anyone has a clue about how the K01 and K02 really came to be,techstudio flat out copied or stole for a better term Efim Dreers design and copied it after he released his knife sharpener and most likely after seeing some of his early work.
Efim Dreer is from Canada and he was doing youtube videos of his different contraptions he made before techstudio ever came along and I remember watching his videos when I first playing around with guided systems like the gatco's and kme stuff at first.
I will say this about the techstudio stuff their sharpener looks more professionally designed and is far more attractive to look at where as the Efim sharpener looks more like there was no thought to styling but none the less the K01 and K02s are just copies of Efim Dreers hard work.
Here is one place where they are sold
