I have used a lot of seam rippers in my time from ergonomic to cheappy. The hands down best seam ripper I have ever used is one made by the other Rodney in LA and it is wonderful! Double ended with a small ripper on one end and a larger ripper on the other with a hand lathed handle from beautiful woods it is a very useful piece of art that I use daily. amazing how much unsewing I do because I change my mind about something.

I am enamored with the "Seam Fix" - my new best find as the knobby tip "erases" all those little thread eyelashes that are left after you rip!

Someone on this board suggested Clover 463 and I love it. It has a very fine tip so it works well on small stitches.

I love the Dritz blue-handled seam ripper. It retails for just over $2.00 at the big box fabric stores. When they have their 50% off sales, I get them for about a dollar. I buy several at a time because they are the one tool that I lose most often. I don't think I've ever had one wear out because I lose it before that happens! Because they are so inexpensive, I don't feel distressed if I misplace it.

I have heard wonderful things about this seam ripper.

My fav is the one that I can grab quickly. I have 4-5 sem rippers.

That rubber tip makes quick cleanup of thos snipped threads.

The Havel is the only one I like. Has nice metal handle and the blade is easy to replace. Love the sharp and curve of the blades.

Clover has two seam rippers that I like. One has a round white handle, the other has a flat brown handle. I think both have the same tip, which is small and sharp. I bought the flat handled one thinking that it wouldn't roll off my table and disappear. I was half right -- it grew legs and disappeared. Mark Lapinsky's "crew" did a comparison on seam rippers in his magazine, and the two Clover rippers were #1 and #2 on their list.

Thanks for the input!
