Havels Ultra Pro Naadripper

The cap snaps on with a satisfying click and stays put in my drawer, which is more than I can say for other seam rippers I've owned. That razor edge made quick work of some stubborn denim stitching without snagging a single thread of the fabric.

I used it on denim and it cut through the heavy thread like butter. The replaceable blades are a game changer since I don’t have to buy a whole new tool. Plus the plastic cap clicks on securely so I can toss it in my sewing kit without worry.

That seam ripper glided through a stubborn velvet hem like it was butter, no snagging or pulling at all. The blade is genuinely surgically sharp. Swapping in the spare stainless steel one was quick, too.
