The best type of love keeps you on your toes. While it should never be hard, it should at least motivate you to spend morning, noon, and night deliberating over every small detail of your engagement ring.
When it’s finally time to go down on one knee and pop that question of all questions, what better way to demonstrate your commitment than by presenting your beloved with a ring that exemplifies how much you know about them?
A knife edge doesn’t sound as great as living on your toes, unless, of course, we’re talking about the ring on your finger. Knife edge engagement rings of stunning, sleek, and modern – and not as dangerous as they may sound.
Here’s what you need to know.
Tiffany & Co. were the pioneers behind the world’s first knife edge band way back in the 19th century, which makes it a lot more of a classic than its modern appearance suggests. Since then, the style has inspired jewelers around the world and remains one of the most popular options for contemporary engagement rings.
Traditionally, the band (otherwise known as the shank) of an engagement ring is more or less flat, maybe with an ever so slight curve on top. This tends to be seen as the most comfortable and durable choice, but it isn’t the only option. If you want to add a little extra intrigue to your ring’s design, then look no further than the knife edge.
Instead of a gentle doming on the outside of the shank, a knife edge band features 2 flat edges that converge together. This creates a horizontal ridge that runs the full circumference of the band. If you’re deep into your diamond lingo, can consider the two sides of the shank to be two facets – just don’t expect them to sparkle.
It’s a subtle but powerful adaptation of the traditional ring design. The two sides of the band catch the light differently, creating an attractive contrast. The effect is very modern and more geometric than the ring designs you’re more used to seeing.
Before we dive deeper into the specifics, here are some practical tips to help guide your decision-making process:

A knife edge band isn’t uncomfortable to wear. If you’re used to wearing rounded bands, then it may feel a little different at first, but it’s not filed to a sharp point or so prominent that you’ll feel it jutting against your other fingers.
One of the biggest factors determining comfort is the size of the shank. A thick band will always feel strange at first, whether it’s a knife edge or a more traditional shape.
As always, you want to make sure that the band fits the wearer’s finger. If it doesn’t, it won’t be comfortable.
The outer rim of the band comprises two separate facets, which meet in the center and form a ridge that reaches around the circumference of the shank. It’s a simple change, but very powerful and modernising even the simplest solitaire design, and giving even the plushest diamond cut a fresh edge.
Contrary to what a lot of first-time shoppers think, a knife edge ring isn’t nearly as uncomfortable to wear as it sounds. First of all, most engagement ring shanks are only a few millimetres in width, so don’t get caught up on the zoomed-in photography. A properly sized engagement ring won’t cut into the finger.
Plus, the knife edge isn’t nearly as sharp as it sounds. You won’t inadvertently create a pain-inducing engagement ring to rival Machine Gun Kelly’s ring to Megan Fox…
Consider bringing your bride-to-be along with you to try on knife edge rings. It’s unlikely she’ll find it uncomfortable, but it’s always worth checking. Next, you’ll want to think about the two key elements of the ring: the metal and the diamond.
Since the ridge or high point of the knife edge ring is a little more vulnerable to damage than a flat or curved shank, a durable metal is important. A high karat gold, while desirable for its rich color, isn’t the best choice – instead, opt for a 14K gold. 18K will still be strong, but not as strong as 14K.
Platinum is incredibly strong, as are palladium and titanium – although platinum is the most popular choice of the three, not least of all because of its incredible shine.
The knife edge shank design brings a really modern, edgy look, so consider pairing it with a diamond shape that brings a similarly contemporary vibe to the ring. The Princess cut is an excellent example of this; modern, icy and edgy, it looks particularly captivating paired with a platinum knife edge band.
Then again, a rounded shape brings a nice contrast. An Oval solitaire with a knife edge band will be a classic for generations to come – or, of course, the OG itself, the round brilliant.
We also love the dual pairing of geometric shapes that you get when you combine an emerald cut diamond with a knife edge Shank. For this one, we may lean towards a yellow gold band, just to keep a little contrast in the mix.
Knife edge rings don’t need any particular care or maintenance – as with any engagement ring, you just want to make sure it stays clean (without using any harsh chemicals) and safe from exertive or risky activities. Take a look at our full guide to caring for your engagement ring here.
We’d recommend you avoid picking a knife edge engagement ring that is too skinny. While it may sound like a good way to avoid any discomfort, the opposite is actually true: A thicker band will create a slightly smoother knife edge, which will prove a lot more comfortable to wear.
It’s a great idea to complement the knife edge band’s edginess with a stark white metal like platinum, and, of course, that stunning, clear center diamond. This design really works best with contemporary settings and diamond shapes, although the timeless classic the Marquise will maximise the ring’s edge.
This one really comes down to personal choice. A knife edge Shank for your engagement ring doesn’t necessarily mean that you have to go for a knife edge Shank for your wedding band. In fact, you may think it’s overkill. The power of the knife edge band design is in its simplicity, so don’t overdo it.
Then again, there’s a nice synergy achieved when the wedding band matches the engagement ring. The most important thing to know is that you don’t need to feel pigeonholed into either decision – it’s all about what you like.
While the name may make it sound tough, there’s nothing hard to love about the knife edge ring design. Simple but effective, this twist on the traditional band is enough to transform even that classic of classics, the round brilliant solitaire.
Keep in mind the fact that some people may find the knife edge slightly uncomfortable, but ensuring that you’re buying your engagement ring true-to-size will help to minimise any risks there.
