Redesign the whisk to subscribe to prioritize ergonomics for professional use.

I focused on expert interviews and illustration. William led CAD and sketching. We worked together on prototyping and logo design.

chuck grip
fist grip
diagonal volar grip
The first insight from user testing was that there isn't a standardized way to hold a whisk. Grip styles were contingent to the ingredients and desired result.

If I’m whisking for more than 10 minutes, it’s almost always in a pot or pan over heat I feel pain in my forearms mainly.

I would whisk a variety of batters and fillings for around 8 - 10 minutes I’d mainly feel pain in the thenar muscles and carpal tunnel

When whisking, I feel fatigue first in the forearm and then bicep. If I were using a whisk it would be to combine ingredients, like you’re whisking dry ingredients together to mix them well.

V7 was selected filleted edges of channel and hull of whisk, added hang hole.

V5 was selected. thumb channel was made wider

V3 was the only model selected implemented a flat side per expert user’s suggestion
v1
phase one
v2
v3
V1 and V2 are too small, wouldn’t allow me to drive through a thicker batter. V3 feels unbalanced.
I’d like to see a flat side on V3
Widen the channel on V5, my thumb feels restricted when changing grip.
V7 feels too long, forcing my hand at the top.

phase three
Hover over dots for callouts!
Inset silicone prevents slipping & wide channel encourages thumb indexing
