Frequently Asked Questions

The Pentalux® is designed like no other fishing rod in the world - bamboo or otherwise. Please feel free to contact me directly if you have any further questions.

What makes a rod a Pentalux®?

The Pentalux® rod is essentially an asymmetrical pentagon. The bottom flat of the rod or the flat which has the guides mounted to it is a broader than standard flat (92 degree strip) with the sides immediately contacting this broader flat cut as traditional or standard penta rod shapes. The top of the rod is then built with two thinner than normal flats thus maximizing the efficiency of the shape as to the application of casting a fly line. This broad flat is essentially cut at a faster rate of change than the other surrounding sides of the rod but the internal tapers of each of the strips matches perfectly to blend into a rod that only wants to flex in plane and is built one to two ferrule sizes SMALLER than traditional hex rods built to cast the same line weight.

What is the advantage of the Pentalux® design?

The primary advantage to the design is in its practical geometry. The rod has a strong tendency or preference to flex in plane. It will not roll over on itself. For those that have flexed and rolled a rod section to find the spine; the same technique will demonstrate that the rod does not want to roll off of the guide plane and once it does it will only settle on the back side of the rod - it will not sit on the side flats of the rod. This results in a rod with superior characteristics for tracking and overall accuracy - the rod effectively only has a front and back flexing evenly in both directions.

Why can the action not be emulated with traditional rod shapes; the hex, penta or quad?

As previously noted, there are three different strip shapes making up the five sides of the Pentalux rod. Further unique to the rod shape is that each of the differing flats have different external rates of change. In other words the broadest base flat has a faster rate of change than the other surrounding sides of the rod. This allows for a strength to weight ratio and taper complexity that cannot be emulated with traditional rod shapes.

When was the first Pentalux® rod built?

The first Pentalux® was built in 2007 and was immediately shared with Ron Barch publisher of the well known rod makers publication, The Planing Form. He published the details of the build in the Jan/Feb 2008 issue. The original rods were all TS shaped tapers which take advantage of the improved strength to weight ratios of the build relative to the traditional hex shape. In 2009 the RS shape rods started - with greater side bracing and overall tracking characteristics than any rod to date.

Is there more than one Pentalux® shape?

Yes, there are two. Depending on the application and taper, I build two different Pentalux® rod shapes. The initial design - now so designated the "T" shape - has a greater strength to weight ratio to that of the "S" shape that was later developed to further improve upon the bracing or tracking effect found in both Pentalux® designs.

Who is the originator of the Pentalux® rods?

My name is Robert Douglas Smith and I am the originator of Pentalux® rods and the original use of an asymmetrical pentagram as a design shape for improved fishing rods.

Where can I try one?

I have a very select list of dealers who occasionally have rods available - as well I have a complete collection of all rod models offered, some of them are designed as fishing demo's. Please feel free to contact me directly for an opportunity to try one - 201.790.3900. Please send me a message of give me a call - If I will not be at an upcoming show, I will gladly send you a demo rod to try. Until you cast and feel one for yourself it is very hard to fully comprehend the improved performance and overall casting experience that is unique to the Pentalux.

Why are the rods not signed or labeled with any ink?

Some of them (although relatively few) are signed either "Smith" or "Pentalux". However, I have always preferred the clean look of Jim Payne, F.E. Thomas and H.L. Leonard rods to those inked with data and thus I generally do not sign or ink them at all unless requested. There are several distinct "signatures" - aside from its shape - on the Pentalux rod. For one, every rod has a serial number cold pressed into the cane on the butt section and the base of the tips (except 3 weights or lighter). Every rod has the SMITH Pentalux® stamp in the butt cap. I double wrap the front and back of every guide - this has been a standard since the first Pentalux rod was wrapped in 2007. I do not believe there is another rod builder in the world who does this. F.E. Thomas double wrapped the top of the guides on his salmon rods as did Gary Howells and early Winston rods but no one else double wraps the top and the bottom edge of the guide foot where the thread ultimately often fails first. I also like to put a very slight flat in the top of the grip to allow the caster to always know where the "track" is.

What happened to original website "PentaluxBamboo"?

Due to poor administration skills on my part the site was lost and instantly purchased by spammers - FINALLY have been able to force the removal of my content from the old site - MY APOLOGIES TO ANYONE WHO ATTEMPTED TO REACH ME IN PAST YEAR THROUGH OLD SITE as nothing thus received. AS WELL PLEASE AVOID CLICKING ON IT AS IT IS USED TO GENERATE SPAM lists!!
