It's Sew Emma 犬の耳クリッパーツール

I was skeptical at first, but the angled blades on these snips make trimming dog ears from my HSTs so much faster. It really saves time compared to using scissors.

My seam ripper used to be my go-to for these, but this little clipper actually saves me a ton of time on every HST batch. The angled blades get right into the corner without nicking the seam, which is more than I can say for my old method. It's become a permanent fixture in my sewing basket.

I used to dread trimming dog ears from my half-square triangles, but this tool makes it fast and precise. The clipper slices through those little corners perfectly without cutting into my seams.
