My latest video on the Alcyon Pro-Cuff 5050-RB (black)https://www.youtube.com/watch?v=iQIdIZhRrW8&index=1&list=PLqe1Hk4m_ku54pNcqheuMVkzWJYlbM8QC
Alcyon make some nice and very reasonably priced sturdy handcuffs. I do like them. They have changed their black finish to be a more durable one. Here is an excerpt of a reply to me regarding their black finish:
"Increasingly the industries are selecting cataphoresis as coating type due to its excellent finish quality, high productivity, reasonable costs and high efficiency. Cataphoresis can be used as a final finish or as an excellent base for other final finishes. It easily fits to original configurations maintaining the design tolerances on parts.
Some years ago we used the black oxide for these pieces but the problem was the corrosion...Now we have not this problem."
So they seem to care enough to evolve things. My main problems are with the tolerances. The poor (not top notch) tolerances mean that the last click of my model 5050-RB and I mean last proper click to where the handcuff is locked and does not flop around, will not double lock. Once you set the double lock and then press on the cuff it rotates, at which point someone with a small wrist who falls could crush their wrist, which is the primary reason for double locking, to prevent this. This is a bad problem in my opinion because for safety reasons that last click is useless, meaning you cannot safely close them quite as small as you are supposed to be able to.
Also in regard to tolerances, the lateral 'play' in the rotating arms/strands is such that in many cases, the tip of the arm clips the sides of the cheek plate (outer area of the handcuff) instead of travelling down the channel it is intended to move. In Alcyon's case, this has created deep and smooth chips of metal being impacted or chipped off. Also it stops the handcuff from positively interacting with the teeth when this happens, possibly leading to problems for police and security officers due to the securing of the cuff being a failure and someone struggling and attacking them.
I hope they pay attention to the email I sent or this message and I want to convey that if these issues are resolved, I think they have some great products. I would like to see a larger wrist capacity on their cuffs, perhaps a separate model, because UK police have a 17% larger size as standard and it is unlikely such a police force would opt for a handcuff with more limited sizing capabilities.
Just my 2 pence worth.
