New Variant:
These calipers work by having an extra arm that bisects the smaller of the two ratios. A couple of people asked me for these… so after a whole ton of experimenting with different shapes, I settled on these.
There are a number of different options for the cases… available from the shop.

Hello!
I can buy a phi caliper with you? i am from Mexico City
Hiya – yes, that’s fine. I think you’ve already contacted me via email… will give a more in-depth reply to that.
Nick did you ever figure out how people use these four-armed calipers with the 0.618 bisection?
Hiya – yea, they’re used for doing micro-blading… the 4th arm marks the mid-point between the eyebrows.
Might be used for other things as well – but that seems to be the main reason.
