The Houzz page that your photo comes from says exactly where the pulls are from in the Questions and Answers, and provides a link for them.

I like the pulls too! From Richelieu.

One thing I am going to say is that, with all those square corners, you may end up with banged up knuckles. We had square edged large pulls and finger pulls in the last kitchen, and I chronically had bloody knuckles. That may not happen to everyone. But it was an issue for me.

Too busy looking. Looks like the 'sale' sign fell out of the frame at Sears.

It is a lot of look, I agree with Paul's sale sign reference, and think I'd end up lots of bruised hips, but to each their own. I notice that they look interesting on lowers but like odd one dimensional squares on the uppers. Can you use these sparingly? Could you do them on the top row of drawers and find something coordinating for the rest of your hardware?

Are the drill holes you will make for these a rather standard spacing? If you don't want this as the look of your kitchen for forever would you be able to replace with something else?

Now that @Paul F. said it, I can't unsee it. Sorry. What do you like about them? The same idea round might (emphasis on might) be better but still busy as Paul said.

It's 6-5/16" on center, which seems like an odd dimension, but Hardware Hut has 1238 pulls with this on center measurement, surprisingly.

The problem I see from a mechanical standpoint is the Offset between where one pulls the handle and where it is attached. I could see that this creates a moment of torque on the screws, particularly in a heavily loaded drawer. I could see them loosening and the holes getting out of round (?)

Atlas has smaller squares if you have been scared off of the big ones.

We have square knobs on all our cabinets and have never had an issue.

@Kate are your square knobs this large and centered in the middle of the drawers? If so, it would be great to see a pic. I’m curious to see how it looks in other kitchens.
