For a superficial scratch, I'd not worry about it. If you used a
razor blade let it be a lesson. If the glass is broken and argon has
leaked out, then yes, have the glass pane replaced. The cheapest way
is to remove the sash out and take it to a good glass shop and have it
fixed. They with fix it up, add the argon and seal it at the edges.
If you take the sash into the shop you will save money by not having
them come to you, remove it, fix it and come back on site to install
it. They will use you present sash frame.
