Adding the Magic Touch


CDC Sedge



Hook:  Daiichi 1150 or 1130 #8-#14

Thread:  MFC 8/0 or UTC 70,  olive or brown

Body:  Dubbed mixture of yellow (old) Marc Petitjean CDC and Light Olive Ice Dub

Thorax:  Red Marc Petitjean CDC

Hackle:  Partridge, natural or dyed burnt orange


Note:  Vary the colors and size to match any caddis species, stillwater, stream or river.  Contrasting abdomens and thorax combinations have proven successful at times. Smaller sizes work well when trout are concentrating on emerging or egg laying chironomids. 


The vicious swirl of a marauding trout in the near shore shallows of a favorite lake reduces the calmest fly fisher to mush.  In the spring migrating damsels draw this response, in the fall just prior to ice up scuds or water boatman might be the hapless quarry.  In late summer emerging sedges are often a popular target, especially those of the Cinnamon clan.  The challenge facing stillwater fly fishers targeting aggressive shallow water predators is devising slow sinking patterns that can be presented with minimal risk of snagging bottom.  Retarded sink rate flies stay in the strike zone longer with the added benefit of reducing the chances of spooking trout as the fly fisher struggles to free fouled flies.


Despite the modern reliance on manmade materials such as foam as source of buoyancy there is an unsung natural material worth considering, CDC.  CDC (Cul De Canard) literally means from the butt of the duck and are the versatile marabou like feathers located around the preen gland.  It was once believed that the preen oils saturating these feathers provided the legendary buoyancy.  With many colors now available the magic of preen oil is a myth as the dying process eliminates the natural oils.  A closer look at a CDC plume reveals the true source of its charm.  The individual barbs of the feathers interlock, resisting collapse and combining together to create a distinct natural source of floatation.  So much so that these marabou clones actually gather air bubbles to further attract fish to the fly.  The challenge with CDC has been taking full advantage of the feather.  Dubbing the barbules is possible by plucking or trimming clumps from the plume but it is fussy.  Winding the feather onto the hook is another option but stem on some plumes can be tough to manage. 


A few of years ago innovative Swiss fly tyer Marc Petitjean introduced the world to a fantastic set of tools appropriately named the Magic Tool.  The Magic Tool allows fly tyers to control materials such as thick stemmed grizzly marabou and CDC.  The tool can also be used to combine and blend different materials together so they can be placed into a dubbing loop such as CDC and dubbing or rabbit fur and Polar Chenille.  Fly tyers are only limited by their own imagination and creativity.  The Magic Tool consists of 3 clear plastic “benches” 2 clear plastic clips and 2 ridged dowls.  The benches feature spring loaded jaws designed to fold feathered materials and isolate the stems for easy removal.  Allowing fly tyers to see their materials and adjust their length according to fly size the clear clips transfer the folded materials from the bench to the dubbing loop.  A source of curious questions for many the ridged dowels are used for adding synthetic materials such as Crystal Flash and Flashbou to the dubbing mixtures this tool easily creates.  Marc Petijean includes a detailed color pamphlet with each Magic Tool illustrating some common uses and versatility of his Magic Tool.  Video clips can also be seen at


Using the Magic Tool is easy.  Begin by choosing an appropriate bench.  Feathered materials should overhang the edges of the bench so they can be grasped and manipulated.  Stroke feathered materials from the tip to the butt standing the individual barbs perpendicular to the stem.  Lay the prepared feather flat on the bench.  If combining dubbing and feathers lay a balanced pinch of dubbing on top of the feather.  Prepare a second feather and lay it on top of the first feather sandwiching the dubbing in the process.  Get into the habit of laying the second feather in the opposite direction as the first, butt to tip.  This pays dividends when combining heavy stemmed feathers.  Grasp the ends of the feathers with the thumb and forefinger of each hand and using firm steady pressure force the feathers down folding the feathers into the jaws of the bench.  If the feathers or other materials fight back or risk breakage heavy thread or fine wire may be used to guide the materials into the jaws of the bench.  Once the materials are folded within the jaws pull the wire or thread out from one side of the bench.  Fur strips can also be combined with other materials.  The fur strip should be no wider than 1/16 of an inch so it slides easily between the jaws of the bench.  Once again gradual pressure works best for easing the materials into the bench jaws.


Once the materials are folded within the bench trim the tips and stems protruding out the sides.  Avoid accidentally opening the bench by holding at the top near the folded materials.  Take the appropriate clear clip and grasp the material tips sticking out of the bench.  Open the bench and slide the clip down removing the blended materials.  Sliding the clip down avoids pinching any material in the springs of bench.  Deliberate motions during the transfer process helps as the tyer becomes familiar with the Magic Tool.  The transfer process soon becomes second nature.  Take advantage of the clear view the clips provide to adjust the grip and measuring the materials to length.  With the materials within the jaws of the clip trim the stems from the dubbing equation.  The materials are ready for insertion into the dubbing loop.  Use the wedge shape of the clear clip and wrist action to ease the materials into the dubbing loop.  For flies requiring multiple dubbing applications the wedge shape of the clip assists opening the loop at the base to surgically slide additional dubbing clumps without disturbing previous applications.  Dubbing wax is not necessary.  The clip is also ideal for grasping fur strips by the tips so the hide can be trimmed without worry of spilling fur everywhere.  Dubbed fur bodies and thoraxes are a durable alternative that pulse and breathe in the slightest of currents or slowest of retrieves.


Tying Instructions



1) Start the tying thread just behind the eye of the hook.  At approximately the mid point on the shank pull down a 3-inch length of tying thread double it around the forefinger and back up to the shank to form a thread loop.  Continue winding the thread back down the shank closing the dubbing loop.  With the loop is closed rotate it on top of the hook shank. Secure the loop back like a tail into the bend of the hook.  Inert a dubbing tool into the loop and let it hang.  Move the tying thread forward to the 3/4's mark on the shank.



2) Take a single CDC feather, hold it by the tip and stroke the feather from tip to the butt standing the indvidual fibers perpendicular to the stem.  Lay the prepared feather on the appropriate size Magic Tool bench so the stem of the feather lays on the seam of the jaws. Lay a sparse clump of Ice Dub along the length of the CDC feather. 



3)  Prepare a second CDC feather in the same fashion as the first.  Lay the 2nd CDC feather on top of the first trapping the dubbing between both feathers.  It is a good idea to get into the habit of laying the feathers in opposite directions.  This practice helps the folding process of stiffer stemmed feathers such as grizzly marabou.  Grasp both feathers by the ends and gently force them down into the bench jaws folding them in the process.



4) Using a pair of scissors trim each end of the now folded combination of CDC and Ice Dub. 



5) Take the appropriate clear plastic Magic Tool clip and grasp the tips of the feathers.  Be careful not to accidently open the jaws of the Magic Tool bench during the transfer process.  The clear clip allows for sizing of the material depending upon where the material is grasped.



6) Open the jaws of the bench, once the CDC is within the jaws of the Magic Tool clip.  Using a downward motion to avoid pinching the material in the bench slide the CDC/Diamond dub mix out of the bench jaws.  With the CDC/Ice Dub mix firmly grasped within the clear clip gently trim the stems away from the CDC leaving just the fibers and Diamond Dub.



7) Place the CDC/Diamond Dub mix into the dubbing loop by opening the loop near the dubbing whirl and sliding the jaws of the clip into the loop.  Pull down on the dubbing loop, pinching the CDC/Diamond Dub mix between the thread strands. Open the jaws of the Magic Tool clip to finish transferring the CDC/Diamond Dub mix to the dubbing loop. Dubbing wax should not be required or used. 



8) Spin the dubbing loop tight until the individual CDC fibers radiate out in a perpendicular fashion.  Wind the now formed dubbing noodle forward to the 3/4's mark where the thread is hanging.  Sweep the materials back with each wrap using the thumb and forefinger.  Tie off the dubbing noodle and trim the excess.



9) Trim the body flush on all sides so that it has a tapered profile from back to front.



10) Select a partridge feather with fibers that are approximately shank length just behind the hook eye. The partridge should be tied in place wet fly style, so that the most prominently marked side of the feather faces the front of the fly.  Create a second, smaller dubbing loop.  Prepare two CDC feathers using the Magic Tool as was done in steps #2-#6. Place the prepared CDC feathers into the dubbing loop.  Spin the dubbing loop tight and wind it forward to form the thorax.  Remember to sweep the dubbing fibers back with each wrap.  Tie off and trim the excess dubbing.



11)  Position the partridge hackle so the fibers flow back over the fly by making a 1/2 turn directly in front of the thorax. Once positioned attach a pair of hackle pliers to the tip area of the feather. Wind the feather forward in close touching turns, 2-3 times is ample. Tie off and trim the excess partridge. Build a neat tapered head, whip finish and apply head cement.  Pinch the head and hackle to further "train" the fibers to flow back.
