Does "Air cutter" has no turn off option?

[Prolbo]

It came to my attention that one of the most energy expensive tools in this game has no "turn off" ability and spends it's charge in first 25~ cuts and then effectively becomes a regular knife. Is that true?

[CalmestGlint220]

indeed but it should be possible to create another knife which you don't upgrade and use as your main knife while only swapping to the air cutter if you need to cut something fast or blue vines

Yes as op said. You make a regular knife to carry with you also. Only use air cutter when needed.

The air cutter is only required for a few specific things in one POI (overgrown surface lift).
And except for gathering seeds they are one-offs to scan other tech.
You can just simply leave it uncharged, untill you go down there.
