Our Story

"We've re-imagined the traditional pen knife to be more comfortable and easy to use and we make them all in our studio here in Boston, MA."


We've re-imagined the traditional pen knife to be more comfortable and easy to use. The form eliminates the pain and discomfort experienced when force is applied to your index finger. By keeping that joint straight you can work for longer periods of time without interruption.  The organic shape of handle allows you to hold it in a way that's most natural for you.

The Ergo Kiwi is a much safer and easy to use precision knife. It’s essentially your hands new best friend.

Product Questions

Does ErgoKiwi work with the Swann Morton Blades?

For now, we can only offer the Kiwi for #2 and #11 blades.  We have not been able to adapt the Kiwi for Swann Morton blades yet but you can be sure we will be in the future!

How does the blade fit into the handle?

The blade doesn't fit into my wood ErgoKiwi properly. What should I do?

Sometimes your Kiwi will be a little tight when brand new, but don’t fret!  Think of your favorite pair of shoes: At first they were uncomfortable, but wear them a while and they fit your feet perfectly.   

Particularly with wood ErgoKiwis, there’s a little science behind this:  The moisture content and temperature where you live may differ from our studio, causing the wood to expand or contract.  We designed the Kiwi to compensate for this, so if it’s a little tight at first, don’t worry, the Kiwi will mold to the shape of the blade.   

We rarely ever encounter any defective products, we are sure to test every Kiwi before we send it out.  It’s our priority that you are perfectly happy with your knife! If you’re still having trouble, let us know right away, we’re here to help!
