Razor wheel--- is there such a thing?

Mike,

I use a scriber to make recessed panel lines, but the "rolling" blade technique actually creates a raised line that looks close enough to pass for the real thing.  The small rotary cutter allows you to do very long single cuts over compound surfaces--- something that just isn't possible with a fixed blade of any length or shape.  By sheer chance I built many models before I ran across one with raised panel lines, and now every other kit I buy seems to have them.  I got a tip to use an Exacto blade to "cut" raised panel lines, but it only worked really well in certain circumstances, like across the top of a fuselage.  I needed something for those compound curves and long lines and the rotary cutter is the best tool I've found so far.  I just wish they made one even smaller!

Why not use a flexible ruler or Dynamo tape and a scriber?

Works much better in my opinion.  

Phil,

Thanks.   I didn't realize they made small cutters like the ones my wife uses for sewing.  The one you identified (28mm)  is a lot smaller than hers, but I managed to find one even smaller (18mm) that should work pretty well for my purposes.  Hope Micromark doesn't find out about these or we'll see them in a future catalog as a raised panel line scriber for 3 times the price.  Thanks for steering me in the right direction.

Something like this perhaps?
