I found this tool and was wondering IF it had any uses in machining. It
is a marker with a KNIFE in it (see www.colorcutter.com). It cuts and
marks at the same time. They sell it for crafting but I noticed they
also have alcohol based versions and that is permanent like a Sharpie
marker so it will work on metal.

I am wondering if there is any practicle use for this in machining? I
ordered a sample but currently am not exactly sure what I will do with
it. Any ideas?
