Part of me feels like the ORB pulls on the uppers will look too abrasive? Too much contrast?

Most commonly, knobs are used for doors, handles are used for drawers. However, it's all a matter of personal preference.

Personally I like the Rh pull better, the Amerock seems more modern. I prefer knobs on doors and pulls on drawers, just my personal preference. However, I have seen a lot of gw pics with only pulls and they look just as wonderful. Your kitchen is coming together beautifully, either will look great.

I think I'm going to do RH pulls on drawers and knobs on all doors. Seems more classic to me. Thanks for your input!

I want to give you a little caution on doing square knobs. They may eventually twist and spin a little from their original position. We had egg shape knobs a few years ago, and they wouldn't stay put. If a round knob goes off kilter, no will notice, but wonky squares might bug you!

Our KD steered me away from the square knobs I had chosen because he said I'd be constantly adjusting them as they turned and looked lopsided. I am forever grateful to him for that warning.

We did all pulls...love the look and we wanted to avoid that build up around the knobs from fingers touching the wood.

Pulls are more Universal Design friendly to people of all ages and grasping abilities.

It's really a matter of personal preference.
For our kitchen reno we went with all knobs.

All Knob Kitchen

Here's the great thing about door hardware: there are hardly any wrong answers, and almost as many right answers as posters on GW! Pulls, knobs, a combination of the two, short pulls, long pulls, vertical, horizontal - we've seen them all, and I don't think I've ever said "What a gorgeous kitchen - too bad they screwed up the hardware!"

Of course that doesn't make the decision any easier, but at least I hope it reduces some stress about the decision.

That looks nice, willtv! I'm curious, though, about why you placed some of the cabinet knobs at the center of the stile, while the others are towards the end?

We did all pulls on doors and drawers for many of the reasons already mentioned by other posters. In the old kitchen, I found the area around the knobs and the knobs themselves too hard to keep clean. Can't say why but it's easier to wipe down a longer straight surface than a small round one :)

I also did a classic style kitchen with knobs on doors and 4" pulls on drawers. I used RH bistro. I really like that they do not take over the look of the kitchen.

In another room, I did use square orb knobs; I like them too but they do twist, so if you're anal about each positioned the same, you may wish to reconsider using square ones.

I am also going with all pulls for ease of cleaning, as well as the way they look. I have square knobs in my LR and I am always having to turn them. It drives me crazy!

I did all pulls except for my small stacked upper cabinets where I did knobs. I have found knobs on heavily used cabinets to become loose over time and am constantly tightening them so they don't fall off.

I'm going with al pulls. It's a transitional style. Here is what I selected.

Thanks for all your opinions! I am for sure not doing square pulls, thanks so much for educating me on this! (I had not thought of that) I think I am for sure doing RH Aubrey for the pulls on the drawers. I don't think they would look very good on the wall cabinets? The seem like they need to be horizontal, if that makes sense?https://media.restorationhardware.com/is/image/rhis/prod1278084_HW07_cl409026?$605w$&resMode=sharp&op_usm=1.0,1.0,5,0&illum=0

We have square, actually rectangular knobs on our upper cabinets and have had for 5 years. I have never adjusted one of them. Mine do have a high relief so the doors don't get dirty but the relief was chosen because I have arthritis in my fingers and I didn't want to be banging my fingers. My pulls on the drawers also have a high relief.
