Rope splicing requires skill, dexterity and strength. It's a mix of science and craft and cannot be 'manufactured' in the true sense of the word.
Hang on you say! What about the MAX Splice from Yale Cordage? They use a 'machine' to splice their rope!
Well… yes, Yale do use a 'machine' but it's still not a case of rope in one end and eye splice out the other.
The 'machine' developed by Yale allows the company to retain the core in the eye of the splice, thereby enhancing consistency in manufacture. Without machine assistance the core would need to be removed and the bury completed by hand.
Have a look at the video above and you will appreciate how much human skill is involved in the construction of an eye splice - even with machine assistance.
