I can't answer your question, but i love crystal door knobs. And what to use them on just my bathroom doors. Was wondering if that would be ok too?

we have 19 crystal doorknobs waiting to be installed next week
crystal doorknobs have been around a long time and i've never heard of them being all that delicate or dangerous

They are solid, so I would think unless you give your kids hammers, you're probably okay.

I'm not sure about newfangled glass doorknobs, but I grew up in a NYC prewar apartment with the original glass doorknobs from the 1920s, and the doorknobs survived my siblings and vice versa. After my parents died, some 85 years after the doorknobs were originally installed, I was nostalgic enough about the knobs that I removed a few to keep as souvenirs. Still in fine shape and working well, and if one was ever used as a weapon, I'd fear for the victim rather than the knob.

I don't know about the newer glass knobs, but the ones in my house are original to the house, and it was built in 1900. They are doing just fine.

I'd do a tad bit of research and find out a bit about the manufacturer, because it could be that Seller #1 has had a bad experience with a particular brand of glass knob.

Not a concern at all. Three kids, tons of old doors and glass knobs.

My grandmother had original glass doorknobs in her house and one of them broke as my aunt turned the knob one day. It cut my aunt's hand badly and left her hand permanently damaged. My aunt was a grown woman with kids at the time. I love the look of glass doorknobs but I wouldn't be comfortable having them in my own home.

Well, I'd not be worried unless they are something manufactured in China or similar - who knows if they would be as durable as those from times gone by.

I grew up with glass (probably not crystal) door knobs and had no issue with them.

I will say though that in our house we chose levers instead of knobs. I know, a totally different look, but so eminently practical...so easy to operate with your arms full, let alone if you have grasping issues. Just thought I'd mention it.

I'd agree that vintage knobs are likely more durable than newly created ones. There are going to be issues with any kind of knobs-there are issues with everything these days it seems. But if it were me, I'd probably try to find authentic, vintage knobs or have a craftsperson make them for me. I wouldn't trust what is manufactured today and available mass market.

Thank you all for your replies!

It sounds like being sure that we're getting a high quality knob is what's most important. (Interestingly - Seller 1 is a large online store, and Seller 2 is a 40 year old family run business in the US.)

I'm thinking that Seller 2 is the way to go (although the comment about a severe cut from an antique knob is still weighing on my mind).

It sounds like a freak accident - the knob must have been cracked prior to that - Maybe from smashing against the wall? Something like that could happen with a drinking glass as well. But it wouldn't be a bad idea to make sure you have good doorstops so the knob wont get damaged that way.
