SirN

This is the home of high quality, custom fitted collars and cuffs of Sir N.

I make unique collars, cuffs and other bondage equpment aimed for the BDSM community, using stainless steel wire rope and aluminum as my materials. My products range from jewellery collars to functional, escape proof locking cuffs. Everything is made to order to ensure you get just the item you want.

All items listed are original designs by me, Sir N, and handmade in Helsinki, Finland, in the north of Europe. There is more information about possible customization options and sizing on each item´s listing.

Completely custom orders are also possible. If you have an idea you´d like to talk about, don´t hesitate to contact me.


I try to make all of my products beautiful and durable in the same time. I think that even though an item might be used mostly as jewellery, concerning the needs of an average BDSM practitioner it should be functional and durable as well. All of my products are designed with durability in mind without forgetting aesthetics. However nothing prevents you from using them simply as jewellery if you wish. All of the materials are such, that they are suitable to be worn 24/7 by most people.


About the different generations of collars and cuffs

Generation 1:
This is my original design for a steel wire cuff. These are simple and affordable, but probably the strongest ones of the designs. They are constructed of three 3mm (0,12in) thick stainless steel cables and tubular aluminum. The G1 cuffs are always locking designs, and provided with the locks. Simple and secure, customizable only for size.

Generation 2:
This is a variation of the original G1 design constructed of tubular aluminum and steel wire. Unlike G1, these have space between the wires making them more belt-like. This design is especially suitable for wider constructions such as posture collars. The G2 designs close with small screws, and have a locking mechanism as an option. They are customizable for size and width.

Generation 3, Generation 3.5:
These are the newest, and most jewellery-like designs, although still very strong. They are constucted of hand milled solid aluminun blocks and steel wire, making them very beautiful and giving them more customization options than G1 and G2 products. I think they are discrete enough to be worn as day-to-day jewellery or slave collars.

As of May 2011, the entire making process of the G3 line has been rethinked, and the lock mechanism replaced with a new, even more stronger model. This makes the collars and cuffs much more suitable for actual strenuous use and real shackling than the old lock allowed. I call this new line of products the Generation 3.5, and it replaces the original G3 collars.
