Hey Metal, hows life?

I just got back from a week out field, my uniform I wore out there would keep even the most gunge-loving piglet happy! Three more washes and I should be able to wear it again.

Anyway my most recent purchase is something I think you would enjoy a lot, hence this email. I know how much you adore padlocks, and locking metal restraints. Well one of my most favorite pieces of kit is my locking ball weights, you know the metal ones that you need an allen key to take on and off? I call them locking since an allen key is not something you always have access to.

Fetters in UK bought out a range with a recessed groove in them, and then a variety of attachments for them. I have two of the attachments so far and aim to get the third, well-marketed (i.e., you want it but it will cost you!) the latest one I brought adds an extra layer of entrapment to the device, it is a locking collar that fits around the groove, I have a pic of it attached and in use on my nuts, let me tell you that thing is on tight, you have no chance of slipping it off over the weight unless it is unlocked.

I hope you enjoy these pics and that you’re doing well!
