Well known for their hybrids, Nickent Golf are making serious in roads into all types of clubs and the Pipe range is a great example.
Nickent PIPE Putter Features: 
Alignment is more important in putting than any other factor. With the new PIPE Putter, Nickent has developed the easiest alignment system ever. The patent-pending PIPE putter was designed with a cylinder pipe shape on the top of the clubhead to provide a 3-dimensional visual readout of exactly where your putter is lined up. Putters made to help alignment in the past were only two-dimensional, allowing only half the visualization needed to sink longer putts. The PIPE putter is one solid block of alignment aide that shows you precisely where you are aimed from any position and any distance on the green. Because it is 3-dimensional, it will also show you what direction to roll the ball from any type of stance or different putter lie.
Cylinder alignment pipe shape on top of clubhead for 3-dimensional readout of exactly where the putter is lined up for the ultimate alignment.
Heavy plug in the rear of the pipe section accounts for 15% of the weight of the putter, while the overall construction is a light polymer centerpiece surrounded by heavier steel.
Expanded mallet keeps the clubhead stable throughout the swing, encouraging a pendulum stroke. P-line face insert is a proprietary advanced polymer composite.
Standard WINN grip and True Temper Double Bend shaft.
PP/001 Putter: 
This Double-Bend Mallet is the original PIPE Putter that took the world by storm in 2005. It is perfectly face-balanced and expertly setup to utilize the PIPE’s best-in-class alignment system. Also available in left handed models.
PP/002 Putter: 
A Center Shafted model of the popular mallet design, this PIPE model easily lets you know where to strike the ball on the face due to the perfect location of the hosel. It is for players who like to take the club straight back and straight through.
PP/003 Putter 
The Plumber-Neck Mallet PIPE is characterized by a horizontal bend just below where the end of the shaft and the hosel meet. This design is ideal for players keeping their hands ahead of the clubhead through impact. This tends to make the putter more forgiving and easier to use, which is the reason it’s so popular.
PP/004 Putter:
The Plumber-Neck Blade features a shorter PIPE section than the mallet and no perimeter bars on the outside of the clubhead. This enables a blade putter with a substantially higher MOI than other blade putters on the market. This design is ideal for players keeping their hands ahead of the clubhead through impact. This tends to make the putter more forgiving and easier to use, even in a Blade model, which is the reason it’s so popular.
PP/005 Putter:
This Flare-Tip Blade features a shorter PIPE section than the mallet and no perimeter bars on the outside of the clubhead. This enables a blade putter with a substantially higher MOI than other blade putters on the market. Putters with flare-tip hosels generally have less offset and are more blade-like in their design. This type of design usually works best for golfers who like to rotate the blade open and shut through the stroke.
