Willowweave Materials
Willowweave is available in 316L stainless steel and titanium, both at the same price. The value of Willowweave lies in the artistry behind her, not in the commodity value of the metal from which she is made.
There are, however, some things to consider when choosing the metal for your commission.
Steel
I feel steel is a better fit. Willowweave is more than the way her bars flow; she is also a story. And steel is a storied metal. Steel has been with us for over 2,000 years. It is part of who we are. It has built our cities and fought our wars. Steel brings a touch of that history to Willowweave.
Practically, steel is heavier. You're unlikely to notice the difference when fully dressed, but when worn alone, steel will make her heft felt. How that plays into your relationship with chastity is deeply personal.
Steel is also warm. When first put on, she will feel cold against your skin, but she will quickly warm to your temperature. As our hands are often cooler, she will feel warm to the touch. I find this to be one of the ways she can become more a part of you.
Titanium
Choosing titanium will reduce her weight by approximately 40%. That can make titanium a compelling choice, particularly if you're concerned about her riding lower.
Titanium is also stronger than stainless steel. For the purposes of a personal restraint, the difference has little practical significance. Psychologically, however, knowing that your Willowweave is made from such a metal may carry a significance of its own.
A Personal Choice
Each metal has different qualities, and the one you choose for her will help shape her character and be a small part of what makes her unique.
