Tried the Smith's sharpener that I got in the States this afternoon.
Pro's.
Well made.
Knife is held very securely by the vice.
Looks awkward to hold but really very easy.
If all your knives are 25° or above, it sharpens them fine.
Con's.
The sharpening stones are not so easy to grip.
Your fingers are pretty close to the blade
If all your knives are 20°, like mine, then the problems start
Basically, if the blade is 1/2" wide or less, the stone sharpens the vice!
You can just get away with 3/4" wide, but very close to the vice closing knobs.
If blades are wider than an inch or more, it works fine on 20°

3. This is on an 1 1/4" wide blade and it misses the tightening knob, but not by much!
