This year, 2025, marks the 35th anniversary of Fisher Putters. Developed and patented in the early 90's by Dr. Dale Fisher, Kevflex is a polymer insert which set the USGA conforming standard for putter face softness, A85, on a Shore durometer. That softness creates roll and traction that makes for a significantly true and consistent putt.
The Edge Series ES5 that we tested this spring measures 88 on an "A" Durometer and is so soft at impact that it's hard to believe how durable the Kevflex insert is - clean and smooth as new after many rounds in sun and rain, through sand spray, fertilizer and aerated greens.
Optimal Aiming Arrows on the trailing edge are clear at both take away and through stroke while the very comfortable pistol grip settled well in both large and smaller hands.
The Fisher Putter Edge Series ES5 sells for $279.00 USD and is available online at
