As Beech Boy says - It doesnt really matter what type of pliers you use.
I think that its the end job that counts.
The Sealey one's work, but I think they are a bit clumsy, especially for thicker wire.
Like TRH I too like the Blue-Point 6" set - though mine aren't reversible - I just twist the whole pliers the very few times I need to do that.
I have also use the old Locktite ones and "twizzle sticks" to perform various special jobs/needs - all types work to some form of satisfaction....but, where Wire Locking is required, nothing beats practice, practice, practice.
