I should have taken a picture of putting on the blades because if you've ever used scalpels and put on blades you'll recognise both the way these blades are packaged and also the way the handles work and realise that we're talking serious sharpness here.

Using them requires a slightly different technique than the standard unripper but nothing too strange.

This section went really fast! The only thing it's not good at is ripping out top stitching where you can't pull the two sides apart and put some tension on the stitching, but I've got the old unripper for that kind of thing. It will take a bit of getting used to but I think they'll be worth it. Thanks Jess!
