Dit is een precise instrument / This is a (precision) measurement tool with exact dimensions and straightness.
So handle with care.
That means tapping it gently; but not hammering, using it as a crowbar and so on.
It is very important that if you accidentally drop it; or think it may be out of line - that you either mark the tool very clearly -- or report this to the mailing list. So that your fellow makers do not ruin their work.
