The "One Fly" Tying Kit™ is for new and experienced fly tiers who would like to try a new tenkara pattern without having to buy a lot of new materials.
The one question asked by most people who are thinking of taking up fly tying is "can you save money tying your own flies?" The answer to that, as for many other questions, is "yes, but..." You can save money tying your own flies, but only, ONLY if you can avoid the slippery slope that catches most fly tiers. You can save money only if you remain, first and foremost, a "fly tier" and resist the urge to become a "collector of fly tying materials."
Tie flies and you'll save few bucks and have a very pleasant and rewarding pastime for when the snow flies, the wind blows or you can't get out on the water. Collect fly tying materials and you'll spend thousands of dollars on esoteric feathers and fibers, hair and hides. You won't (can't) save money if you buy materials that you will never use.
Each "One Fly" Tying Kit™ comes with a package of 25 Daiichi hooks, the materials required to tie 25 flies and a pattern sheet that provides easy to follow step-by-step instructions. There will be very little waste and you won't have to buy a whole rooster neck or partridge skin, or enough yarn for a whole sweater, just to try out few flies. If the fly works and you want to tie it on a regular basis, then you can buy the normal quantity of the required materials.
At this point, the following "One Fly" Tying Kits™ are available:
Utah Killer Bug
Pink Chenille Worm
Takayama Sakasa Kebari
Not only has the Killer Bug been my most productive fly for as long as I've been tying it, it is the one I get asked about the most regarding where to buy the required materials. I also get asked about it by people who find it hard to believe that a fly unlike anything they've ever used can be so very good. I've changed the kit from the Killer Bug to the Utah Killer Bug. The Utah Killer Bug does not require a marker to color the yarn, which makes the fly simpler and the kit less expensive.
The Killer Bugger is a cross between a Killer Bug and a Woolly Bugger - basically a Killer Bugger with a marabou tail. The extemely mobile marabou tail adds a significant "trigger" for strikes. It changes the fly's profile from scud/cranefly lava/caddis pupa to helgrammite/minnow/leech. Plus, the slow pulsing manipulation tenkara masters use gives the Killer Bugger a lifelike swimming motion. The Woolly Bugger is successful everywhere but as it is usually tied, it is too large and too heavy for tenkara rods. The Killer Bugger is not too heavy and not too large, and is a good match for tenkara.
Dr' Ishigaki's Fly is even a bit simpler, with just thread, a hook and some hackle. It's the only fly he uses, though, and perhaps that should tell us something.
The Minimal Dace is an extremely simple bucktail that has worked well for me. Although you need only a bucktail and a spool of thread, the fly mimics many species of minnows that share a common coloration: brown back, black stripe down the side and white belly. Tied sparse, and relatively small (size 12), it is easy to cast with tenkara rods yet attracts very nice fish.
The Pink Chenille Worm is a variation of the San Juan Worm. It is small, bright pink and tied on a small hook. It is an extremely effective fly and is about as easy to tie as you can get. It is also very inexpensive. Can you save money tying your own flies? If you tie Pink Chenille Worms the answer is a definite yes!
The Sakasa Kebari "One Fly" Tying Kit™ comes with Hungarian
Partridge hackle, Pearsall's Gossamer silk tying thread, and a peacock
eyed stick. This is a classic Japanese tenkara fly which is surprisingly
similar to the reverse hackle flies developed in Italy for pesca mosca
Valsesiana and to the sparse North Country spiders that have been
catching fish for hundreds of years in the UK. It even looks a bit like
the venerable Royal Coachman - and for brookies is just as effective!
