When I first saw a 'seam-scraper' I thought, why? I've got one of those, it's called an X-acto #11. No no no, I finally bought one of these when I had a bigger project and quickly realized it has powers far beyond those of a thinner blade. The angle of the cutting edge and the overall weight give it a unique ability to get into tight corners and plane a surface down to a nice shine. It has quickly become one of my new best friends, literally a magic wand that when waved over your model, all the surfaces align. I find myself using it a lot now, a classic example of something I never needed before but now I can't live without. If you (like me) ever scoffed at this thing, give it a try. It's impressive how well it performs. Now that I've tried it I will always have one on my modeling table.

Very helpful for cleaning up seam lines on panels or edges of small parts. Also good for scraping glue of off your work surface.

Awesome product. This was a replacement for the one that I lost. Great for seams that you don't want to use the backside of a knife blade for. Very easy to use. Really, it's hard to be without one once using one.
