Superfit Shank, Here to Woo You with its Special Abilities
As a specialist in modifying rings that spin to be more comfortably worn, I have written on various possible solutions previously. See my related blogs on speed bumps, butterfly springs and Fingermate hinging shanks.
Jumping right in it’s time that I added to the reviews of possible big knuckle fit solutions with this article on the Superfit Shank.
Right off the bat I’ll let you know as a custom jewelry designer who loves to use engraving and details on rings I find the Superfit shank to be fantastic where details are concerned.
How the Superfit Shank Works
To open your snugly fitting Superfit shank you can use an ordinary ball point pen. You press the point into a small depression and that unlocks your shank. It opens up and easily comes off your finger. I appreciate that you don’t need a fancy tool or complex method to open it. When it’s closed, your ring is smooth and the hinges are not obvious.
Do Hinging Shanks Hold Up Over Time?
One of the things that I’ve been asked is how long do these things last?
My answer is that anything that moves that you use every day isn’t going to last forever. It will need some maintenance, oiling and occasionally more.
I’ve observed that with normal wear, the maintenance needs of hinging shanks in general are few.
Warning About Hinging Shanks
If you have a thin ring, like two millimeters wide in the area of the hinge, my opinion is that it is too narrow. For your ring hinge to have a long life of reliability, I feel you need a wider ring shank. Ideally three millimeters or wider creates a better foundation.
Additionally I recommend using Superfit shanks only on rings with a good depth to stabilize the mechanism. If your ring is made in a lightweight or thin way, additional support will need to be created as part of the installation process. In that case we put in an under-bridge of metal under the upper part of the ring to support the hinge mechanism. So even if your ring is made lightly, we can address that.
If you do physical work with your hands involving lifting and gripping a lot, your hinging shank may run into problems sooner. Lifting and gripping can change the shape of your ring from round to more oval. In a normal ring that can be problematic and weaken your ring. In a ring with a hinging shank, it can mess up the whole mechanism. It’s smart not to overstress a ring with a hinge in it.
Who Needs a Superfit Shank?
Anyone with a knuckle to finger differential of 2.5 sizes or more probably needs this. Read my description of the knuckle to finger differential.
I had a client with a 4 size differential and the Superfit was the only solution for her wedding ring. She needed her ring to clam shell open completely to get beyond her arthritic knuckle.
How Much is a Superfit Ring Shank?
The average retrofit starts at around $1200 – 1500, but we really need to evaluate each ring to make sure we are taking into account anything out of the ordinary or foreseeing any changes that you may want. For example if your ring has hand engraving in its design we’ll need to engrave your new shank to match the balance of your ring. That would cost more.
I’d say 80% of the rings are pretty straight forward and we simply add the new shank. Superfit pre-makes many thicknesses of shanks in straight shapes. Most rings in the 2.5 – 4mm range fit in this price range. If we need to use platinum, that’ll bump up the cost as well.
The other 20% of rings are more involved retrofits including – eternity bands, bypass style rings (where the shank is not straight), euro shanks (square bottom), extra wide rings, hand engraving or invisible sets. Most of these can be accommodated, but they require extra care, both in figuring out special solutions and in execution. Our goal is to preserve the special details of your design and make your ring a joy to wear.
The Custom Ring’s Best Friend
For oddly curved rings, engraved rings, rings with patterns and openings going on all around your ring, in other words unique rings off the beaten path, I’ve found Superfit to be the most versatile in allowing me to hingify your ring seamlessly. Thumbs up!
