These Curves are now around 25% stronger than their predecessors while still retaining long fine needle sharp points which are now extra durable. These are highly effective in a whole variety of rig presentations (perfect for the Ronnie Rig) and their quick turning, anti-eject shape combined with a needle sharp point ensures exceptional hook holds.
The initial launch of ESP Cryogen hooks in March 2016 caused a massive stir with discerning anglers quickly recognising the distinct technical advantages they offered. They were the result of over three years of development and field testing which culminated in a new standard in strength and point durability.
New manufacturing techniques including both high temperature and cryogenic tempering have produced significantly stronger hooks with more durable, long life points.
Cryogenic tempering is a process used to improve the molecular structure in steel which in turn reduces stress and improves strength and wear resistance. It is used in many disciplines with Formula 1 engine parts being a classic example.
Bench tests on initial samples proved to us that the new tempering processes combined with improved designs and heavy forging resulted in hooks that were 25-30% stronger than other PTFE coated carp hooks in the same wire gauge. We subsequently sent the hooks for independent scientific testing on hardness and tensile strength and the tests carried out confirmed and supported our initial findings.
So rather than having to improve strength by simply increasing wire gauge, new manufacturing processes have allowed us to maintain optimum wire gauges for each size which allow for fine, ultra-sharp needle points which are now more durable than ever.
