@hj No se on varmaan sitten just niin.

I eat proper steaks and stuff sometimes and use a "proper" knife. Those 1e ikea glass plates don't have any marks. It's a freaking burger patty. You could cut that with a butter knife if you wanted to. It doesn't need a specifically designed cutting platform underneath it...

The family plates at my mom's are over 30 years old and they have little to no marks. Plates aren't supposed to be damaged in the eating process.

As for assembling/cooking surfaces: metals exists. Wood is not practical, especially in a restaurant setting where those are supposed to suffer more abuse than in the home kitchen. Wood isn't approved for any allergen usage, because it can still contain some even after wiping clean with alcohol/whatever. Metal surfaces rock on.
