Blade Putters are the traditionalists weapons of choice. Jack Nicklaus won almost all his majors with this style of putter. Blade putters give excellent feel and touch and many players like them because of their soft lines and traditional look.
They tend to be fairly heavy putters and certainly feel like powerful tools in your hands, so they're excellent on both slower greens and faster greens if they are made of softer metals or have an insert. They are heavily toe weighted putters, so will only really suit an open-square-closed stroke.
The Odyssey #9 model is a modern blade. As it's a stock head design in the Odyssey line-up, it's available in many different models ranging from the original White Hot insert putter right up to the latest high-tech versions. These are beautiful putters that put a great roll on the ball and have great feel.
Phil Mickleson used an Odyssey #9 model for the majority of his playing career.
The Wilson 8802 is the absolute classic blade that was favored by players throughout the 1950s and 1960s and survives until today in various forms and models some with inserts and many attractive milled forms. It is also one of the most copied putter shapes, so it's not just Wilson who have made blades like this.
Though there isn't much technology in most of these putters and the sweetspot is therefore quite small, you won't find a putter that looks purer and feels better than this one.
The Yes Sophia is one of the best models manufactured with Yes' C-Groove technology which gives the ball an amazing roll. Although the feel isn't quite up to its milled or insert-faced rivals, this putter does offer technology that can help you make more putts and is available at a low price on the used market.
It may in fact be the best value second-hand putter purchase in history... In 2010 Jim Furyk picked up a used Sophia for $39 in a discount golf store and then used it a few weeks later to scoop $10 million in the season-ending Tour Championship!
Although they are not used by many of today's pros, the great blade putter users of the past have been amongst the greatest putters of all time, so there's nothing to say you cannot be successful with one today.
And there's one thing that's fairly certain with a blade putter: once you've found one you like, you'll keep it for a long time!
