What to open the bottle with

[Robby Zhu]

"This is the gadget we open the bottle with."

Can I re-phrase it as:
This is what to open the bottle with.

According to some grammar pattern, these two sentences are the same. But do you think the second one is awkward?

This is what to open the bottle with.

You can. It would sound a little more ordinary to say This is what you open the bottle with.

Thanks for your confirmation, owlman5.
