I have tried to use it every which way possible. I need more than two hands to even partially make it work.
Slitit Blister Pack Opener

Stop cutting yourself when opening those miserable plastic blister packages! Slitit is the simplest, safest cutting blade I've ever used. The blade is cleverly recessed in an easy grip holder.

This plastic package opener does a better job tackling frustrating packaging, like clamshells and blister packs, with a super tough stainless steel blade. The curved handle protects your hand from sharp edges and the blade when you use it. Line it up, push or pull, and get to the good stuff faster.


The Slitit clamshell opener was born out of frustration, a word often used when talking about this tricky type of plastic packaging. Maker Caitlin Schwartz struggled to open a packaged hair straightener and even injured herself in the process. She paired up with her sister Kirsten—a fellow fine artist—and their mechanical engineer father to create a better-working and safer solution.

Slitit’s stainless steel blade is molded into a contoured, tubular handle. This design choice was a deliberate one. The handle gives you a good grip on the task at hand, plus it protects your actual hands from cut plastic shards while you’re slicing away. Best of all, this cutter is simple to use. Just line it up, push or pull along the problematic packaging, and rejoice at how much easier that was. more Their Story
