I use Clover.

I've used almost all of them but I keep going back to the single edge razor blade like my "home ec" teacher taught me. :D

[QUOTE=RavenLunaStitch;5988814]I know there are lots of bells and whistles like ergonomic handles, lights, etc., but I'm asking about the business end of a seam ripper. Sharp enough to work well without destroying fabric in the process and one that will last a while. I didn't care much about this until I started taking apart clothing items Bonnie Hunter style for some scrappy quilts. We talk a lot about other favorite tools but I want to know if any of you have found a real winner that you will keep and use for a long time?[/QUOTE
Mine best one came with my machine, left behind by a previous owner, so I don't know what it is called. It looks like a miniature medical instrument. It is thin stainless steel with a curved very sharp edge on the curve. I guess I have had two of them for 20 years and they are still sharp. The best thing about them is that you can slip them into a seam and cut threads without cutting or snagging you fabric. My guess is that they are designed for professional seamstresses, alterations and such since I have never seen them in a fabric store. Someone who does this for a living might be able to help. Eleanor Burns uses her rotary cutter but I would not attempt that.

Thanks to all who tried to help me with FMQ--I haven't come close to mastering the tension thing but at least can make an ugly stitch that does not pucker.

When I use clothing for material, usually cotton and flannel shirts, I don't un-sew them. My rotary cutter cuts very close to the seams with little waste. I wouldn't use the cloth that was in the seam area anyway so I make quick work cutting any shirt or skirt.
peace

I like the one DH turned for me on his lathe - it has turquoise inlay and 2 different size "rippers". They tuck into the ends of the turned tube

Wow! He does beautiful work -- that is a work of art. Amazing!

clover is the one for me.. mkc nice seam ripper. your husband does beautiful work..

I like my clover seam ripper, but a lot of the time I use my small rotary cutter-maybe 28mm? and carefully pull the seam apart with one hand and just touch the threads with the cutter with the other hand and it is really quick to unsew. Have to be careful doing that, but I love how fast it is.

I don't have one of these, but it is an awesome seam ripper according to one of my friends...out of my budget...the flat blad sounds like what annel described.
