Havel's® #61 碳鋼微型刀片（5 片裝）

I’ve been swapping out blades on my micro knife handle and these carbon steel ones cut through thick plastic packaging like butter. The ultra-thin profile gives me way more control for detail work than I expected.

I'm on my third pack of these for cutting stencils and plastic film, and the ultra-thin blade hasn't dulled nearly as fast as I expected. They pop into the #81067 handle without any fuss and make clean, precise cuts on thin paper without tearing.

The ultra-thin edge on these blades glides through plastic wrap and cardstock like they're not even there, which is exactly what I needed for my hobby work. They fit the micro handle snugly and hold their sharpness longer than I expected for the price.
