It's common as PPs have indicated but I've never liked that look personally.

No pulls has been very, very common since the 80s in the U.S. So no, not weird.

I've never lived in a house which had pulls on the cabinets.

The only issue would be wear and tear on the bottoms of the cabinets. Years of grabbing them at the bottom will show on the bottoms of the doors but if that doesn't bother you there's no rush to get handles. They're not required or anything. They can change the look of your kitchen, though.

The house I grew up in for twenty years never had pulls/handles.

If it doesn't bother you, then don't worry about it.

We bought a newly renovated place a couple years ago. Didn't have pulls / handles on the kitchen cabinets, and I just realized we've never put any on, so they cabinets are kind of naked. Is this weird? Do I have to put pulls on them? I'm so used to just using them as they are...
