Went through 6 layers of duck canvas and folded denim like butter
I make canvas tote bags and repair work jeans for my husband, and my old craft-store shears used to bow apart the second they hit a flat-felled seam. These Cosari 10-inch shears went through 6 layers of heavy 12oz duck canvas and a folded denim hem like room-temperature butter without the blades flexing apart at all. That quiet, crisp metallic snick-snick sound when you glide down a 36-inch seam line is pure sewing ASMR. Quick tip: wipe off the thin factory protective oil on a scrap rag right out of the box—that's how you know they're real forged carbon steel and not cheap stamped stainless.
