Portable stock

The idea with this tiny stock is that it is the perfect alternative to e.g. a pair of handcuffs e.g. to a fetish party. Not only because it looks better, but also because it is better to the masochist having to carry it around all night (?).
The stock that I've made here, is constructed from two layers of 15 mm plywood, which are glued on top of one another, giving the stock a thickness close to 1¼". It has afterwards been cut out with a compass saw.
Then the two plates intended for the padlock have been added, as well as the hinge at the opposite end.
The surface has been treated with 3 layers of matt black paint, and at last it has gotten another 3 layers of clear lacquer to supply the glossy surface. 
Please notice the shape of the hole intended to be around the neck. The drop-shaped hole is giving a much tighter fit, without troubling the larynx. This for two reasons;

1/ the safety perspective, as I like to use my masochists more than once ( I'm not fond of disposables anyhow ),

2/ it gives the opportunity to grab the masochist by the stock, without risking to damage him/her.  ( SMart, right ? )
