I got the HPA split ring plier. It is pretty simple, but has special saw which can open strong and big split ring wide open even for big treble hooks. I tested with 300 lbs big Varivas split ring with Owner ST76 5/0 and I have little problem to insert ST76 5/0 into the split ring. The retail price is $49 including pouch. I feel the price is pretty stiff. It seems anything associated with France is pretty expensive. size comparison with Duel GT plier and SSplit-Ring Pryers by Texas Tackle.
