Great idea if it would work
11/08/2019 by Diane
Bought this product to make opening those hard plastic packages open a lot easier. I tried it on 5 different packages and it doesn't work as easy as it says it does, ( like a hot knife through butter). Not true. The only way I could make it work is to cut at an angle and that was hard to do because of the long straight edge.
Will get easier with testing

really happy to receive this new item, but unfortunately it does not work as easily expected....not giving up on it as yet as I'm hopeful that it is just me and not the Slit-it, as I bought several to give as additional Christmas gifts. Do hope to get a better grasp on using this item as I'm sure it will end the difficult task of opening many items that are purchased in the future
Awesome new tool to open those plastic packages

This device is awesome! I can't believe that someone had not thought of it before! I ordered two additional ones as gifts.
Kitchen Staple!

How many times have I cut myself trying to get into a hard blisterpacked something! This solved the problem. Easy to use and does the job. Bought one as a gift, too.
not ideal

Plastic Package Opener

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
