Seam Ripper

Seam ripper? Never heard of that one. I'm assuming you meant Panel Scriber like this:

I might have to try it out on some spare parts and compare them from the one I use now.

Use a Panel Scriber, or a Tamiya/Olfa P-cutter, or a needle in a pin vice.

Using a sewing seam-ripper would, just skip & wander off-line, or just dig trenches, as the tip isn't really sharp enough to use without some force.

The seam ripper that my wife has would have to be held almost parallel to the surface to scribe a line.  That seems like it would be hard.  Also, the shape has no surface parallel to its axis that is straight enough to hold against a ruler.

For creating panel lines I have used Tamiya's Scriber and a METAL straight edge (Dont use a plastic ruler.  How do I know?  Yeah.....  lol).   You have to start really light though and make many passes.  Works great though.

Hi;

   Everyone is going to say Oh Gee he's real old school . I don't own a panel scriber anymore ( broke the tip while working on a model .) I now use a Number 11 blade backwards in the groove after I file the end smooth .

    This worked before the scriber and still works now . I use Label Maker Embossing tape for my guides .Works okay for me ! The biggest thing to remember is , a gentle touch works best !
