Knife holder for cutting food

Hey this is Noam from the New Orleans Chapter. I had a request from the community for a easy to use knife holder for cutting food. We looked at the library but did not see anything suitable for this application. After speaking with the user we decided that a simple ‘back and forth’ motion of a saw handle might work best. Attached is a diagram showing the handle and the knife, the obvious difficulty being a sturdy attachment. I do have a few ideas on this, and am working on a prototype, but I wanted to see if anyone had tackled this design/geometry before.

Thanks-
Noam

I know @imtiaz is working on a solution for eating that interfaces with the hand in a different direction, which may get you part of the way. Also, @MMC_Pran didn’t you do a chef knife attachment before?

Thought is if you can share your designs might give inspiration/ save @noamplatt some work.

Hi @noamplatt

May be this will give you an idea, something I’ve been working on.
This post will show you a picture of a cuff holder with a utensil bent at 90 degrees.
The next post by @KenHackbarth is a great adaptation to mount the utensil sticking out of the palm.

But I think you want more of a sawing motion, I think trying the Personalized Cuff Utensil Holder, with the utensil holder mounted at 90 degrees would work. Something like this.

Hey @MMC_Chad ,@imtiaz, and @KenHackbarth Thanks for the responses- is there any way I could get the Fusion file mentioned in this post ?

I would like to print the above Personalized Cuff Holder and see if that is a workable solution. I know overall hand strength is an issue with this client, and I am curious to see what she thinks of the device.

perhaps adapting the utensil holder dovetail geometry and adding a solid vertical handle (instead of the loop handle shown above) with the dovetail receiver would be a really elegant solution. Wedges then could be used to secure the knife.

Tagging a local maker @James_Cat to get this on his radar. -

Thanks-
Noam

Hi,

You can find the Personalized Cuff Holder here:

  1. Info on MMC
  2. Thingiverse - You’ll find the open SCAD files here
  3. Ken’s instructions on how to customize it on his website here

Hope this is a good start.

Hi all,

My Personal Fusion 360 license expired yesterday - very frustrating! I contacted Autodesk and am currently waiting for them to renew my license…

@noamplatt, are you looking for the Fusion 360 file for the 90 degree angle or more? The cuff itself was implemented in OpenSCAD.

Thanks,
Ken

Thanks for the resources, the customization guide is very comprehensive.

@KenHackbarth - that is exactly right, I am looking for the fusion file for the ‘90 degree angle’ holder, I plan to remove the loop and replace it with a straight handle
