The Crucible 2.0

Crown molding

The Crucible is a head-only, ultra-minimalist, piercing chastity design inspired by The Alchemist full-coverage anatomy-molded chastity cage. The Steelwerks Extreme commitment to true, custom chastity cage perfection, is made manifest here by our exclusive process of personalized impression molding of the wearer's unique anatomy. The perfect fit is then precision machined from a solid ingot of titanium. A locking pa chastity piecing keeps him chaste in an opulent organic form and a finish reminiscent of liquid mercury. Nonpareil attention to every made-to-order detail is a SteelwerksExtreme mark of distinction.


The Crucible of your desires can be precision crafted to include the entire range of SteelwerksExtreme customization options; discipline screws, choice of urethral tubes, piercing adaptations, standard locking bladder release plug, and the entire palette of anodized titanium colors. Model shown features integrated urethral tube and prince's wand style locking urethral tube, double security custom spanner wrench locking washer bladder release. Locking aspects feature our proprietary locking S-screws. Retention ring at the posterior edge ensures a secure fit at the shaft, supported by precision custom molding to the glans.
