Several years ago i made this small knife rest, a variant based on the original design by Tormek forum member Herman Trivillino.
Mine is being used for reprofiling/sharpening various blade shapes & sizes (flat ground is ideal, but saber ground is also possible), from the small blades in Victorinox knives up to expensive professional gyuto's with 210 mm blades.
A possible problem is that you would have to make such a knife rest yourself, as Tormek still doesn't offer something comparable.
I used a piece of Torlock cut from a Tormek SVD-110 tool rest (which remains functional afterwards btw), a few pieces of scrap aluminium & some metal screws.
A very important aspect is getting that piece of Torlock as square as possible, for which i used files and a micrometer.
With access to a precision milling machine it would be a piece of cake.
On top is a piece of 0.3 mm thin fiber-reinforced PTFE tape, which works very well for moving the blade across the platform and also to avoid scratches while doing that (up to a point)
For more blade protection i use plastic packing tape on the blade surface as well.
When used in conjunction with just enough water in the trough so that it doesn't splash the platform the tape lasts quite a while before i have to replace it with a new piece.
The lowest angle i can grind to is ~20 degrees inclusive.
