Hello HaiPaio,
thanks for your comment. Almost the whole blade is not fully supported in the jig, which makes the blade move and making it slightly wider in the middle (smaller edge angle). The gap, after cranking the screw down, is 1,25 mm while the blade is 0,6 mm thick. Only the outmost parts contact the blade. Thanks to Rich and Ken I could confirm the clamp is in spec, so no big (or even small) deal. Some cardboard was enough to solve that.

Thanks Rich and Ken!
I will tinker around some more with the jig. It seems I need to shim it, even cranking it uncomfortably hard won't close the gap enough and the blade isn't fully supported in the middle, creating a small "smile" in the grind.

Hello everyone,
I ordered a KJ-140 jig for grinding thin, wobbly blades (like from carpet cutting knives) and when I received it today, it is curved and the gap in the middle is 1,4 mm wide.
Can someone please tell me if this is intentional or did I receive a faulty product?
Greetings
Eric
