It’s always pleasant to find new functionality in a time honored tool, and scissors being the life blood of a fly tier, it’s even sweeter to find something that raises the bar on the traditional implement.
When I converted from inexpensive fly tying scissors to surgical scissors, I needed to relearn how to use scissors, as fine tips and tungsten inserts did not play well with brass wire and hook shanks. I needed to learn to care for the scissor and be judicious in its use – or risk destroying them quickly. A cut toward the hook shank was now a dangerous move, risking catching the shank between those fine points, in addition to the unwanted material I was removing.
After using Iris surgical scissors for several decades, I find myself relearning how to use scissors all over again, this time to avoid removing an errant fingertip, or accidentally severing a Carotid artery.
I was recently gifted a set of Mizutani Kava II scissors from Japan. Mizutani scissors are among the premier makers of barber shears and hair cutting scissors for upscale hairdressers, and have been making them for over one hundred years. Their handmade scissors are known for outstanding edges and meticulous craftsmanship and can cost over a thousand dollars for the high end models.
Mizutani scissors use unique steel alloys in their construction, designed for longevity, and ability to hold an edge on the blades. “Nano powdered metal,” Stellite (High Cobalt content), Damascus, as well as specialty alloys containing Cobalt, Molybdenum, and Vanadium are used in the different styles of Mizutani scissors. “Nano powdered metal” is a term describing the construction of steel by first reducing it to tiny particles, then using heat and pressure to blend the powder into a steel free of impurities, whose ability to hold an edge is unrivaled.
My scissors come in a small box with a Certificate of Authenticity, and the name of the craftsman that made the scissor. Each has the serial number etched on the blade to verify their authenticity versus a potential fake that proliferate in this high priced market. The fly tying scissor is much smaller than traditional barber shears, and only cost about $150 each – which is comparable to mid-range surgical grade scissors from a medical supply house. Each scissor case contains a suede glove to contain the scissor, a small tube of specialized scissor oil, a ratchet device to tighten the unique screw used in the scissor, and several band-aids to use while relearning how to use the scissor properly …
… that’s right, something to prevent your bleeding out – after you do something really stupid …
Mizutani has released their 4,25″ fly tying scissor in Japan, called the “Kava II” scissor, using the same Nano Powdered Metal composition as their traditional barber shears. I was recently gifted a set of these scissors and after a couple of uses, I find myself describing them as, ” …other .. worldly.”
Mizutani scissors come with a warranty covering materials and craftmanship for 30 years, and these can be resharpened via a Mizutani certified shop or by mailing them back to Japan. Resharpening the scissor currently costs between $70 and $100 US dollars (via Japan), depending on the prevailing exchange rate. Our current environment will also be subject to changes in both the Yen/Dollar exchange rate – and tariffs .. which the current quite administration is fond of wielding and/or repealling.

The scissor comes with several screw in tangs that increase the number of fingers participating in the grip (can be added to either left or right handed), and serve as a stand to lift the scissor off the work surface, ensuring it’s not scraped across your desk each time the scissor is added back into your hand. Many fly tier, like myself, tend to put the scissor down when not in use, then hunt for it later when needed. Typically we drag it across to work surface in the process, removing whatever finish the scissor has over time.
Note the screw shown in the above illustration is not a traditional screw used for tightening scissors. A small coin shaped ratchet comes with the scissor that allows for tightening or loosening the screw, which controls the tension required to close the scissor completely. This ratcheted adjustment turns easily and is a very smooth tension adjustment. I set the ratchet tighter a few notches to test how much it changed the tension, and it was minute, implying a lot of adjustment is available to the user.
Most scissors have a design weakness due to the steels involved. The steel of the screw is typically harder than the steel used in the scissor body. Over time, the effort needed to cut tough materials like wire and feather stems, distorts the screw hole as the screw moves minutely against the screw hole, and this expansion becomes unwanted “slop” into the action of the scissor. As all documentation accompanying the scissor is in Japanese, I am unable to confirm the scissor and screw are identical steel, but the 30 year warranty suggests that’s the case.
Surgical steel is typically Stainless (for antiseptic purposes) which is a “soft” steel and the hardened screw can easily deform the screwhole with moderate pressure (and/or considerable use). A good pair of iris surgical scissors will last me somewhere between 2 and 3 years, as fly tying is more abusive to scissors than the minor tendons and flesh of the human eye.
Use and Abuse
I have completed several dozen trout flies through the tying process, and can comment on both the new function and dangers these scissors represent. What I cannot speak to is the prohibitions the maker insists upon – and what shortens or lengthens their lifespan, as I am both unable to find the maker’s prohibitions nor able to translate Japanese.
What’s completely different about these scissors from other high end scissors, is these are two razor sharp knives joined with a screw, these are NOT scissors as we know them.
You DO NOT run your finger down the blade as they will filet your finger instantly. These are conjoined knives or razor blades, and you need to keep your fingers, your children, and everything else away from the “business end” of these scissors.
The three-pronged stand and the increased height of the scissor from the bench makes it easier to find on your work area and begin cutting, and is a welcome option that becomes instinctive quickly.
I tried the scissors both with and without, the three pronged “stand” and found the three tangs do not get in the way whatsoever and are quickly forgotten.
If the finger-extension tang is used on the rear of the scissor, it has just enough weight to tilt the scissor off of its three point rest and make it sit upon the work surface point upward …The weight of the scissor borne by the two rear tangs and the rearmost “grip extension” tang. That does not imply you will impale yourself on the point if you aren’t careful, the points on these are not thin and sharp, rather a fine general -purpose tip versus something “needle sharp” and dangerous.
My default configuration is all tangs attached; three on the scissor as the stand, and the larger tang attached in right hand mode to increase the fingers used in the grip.
I would describe these scissors as an outstanding general purpose scissor usable for all fly types and sizes. They are not “delicate” nor do they seem fragile or damage prone.I would feel comfortable taking a large “whack” out of a spun deer hair bug, a heavy saltwater fly, or a smaller trout fly. Their size and design makes the scissor your “go to” option for all tying, rather than some needle pointed scissor that only handles small flies and fine materials.
New Functionality
A scissor this sharp requires you to think outside the “box.” You should not cut towards your fingers, nor cut towards the shank if your view is obscured by a big gob of marabou or a thicket of spun deer hair.
The scissor is so sharp that most of the tactile feel of the cut is gone. You don’t feel the individual hair strands parting when you close the scissor, and the blades are so sharp they part the material effortlessly. Tying something like a Goddard Caddis and cutting toward your fingers as they hold the bend of the hook, is unwise. It’s likely that your fingertips would offer little resistance to the cut and only the spurt of blood will clue you that you have cut too far … and then the pain will hit.
Flattening the bottom of a Goddard Caddis? Hold the fly in your hackle pliers and keep those sensitive fingertips away from the cut. Trimming a Bass Popper? Large hooks offer more safety, but make sure your fingers are visible and not covered by untrimmed hair …
Razor blades can cut materials simply by applying tension to the item as it touches the blade. This same cut is available from Mizutani scissors. Touch the point to the thread, and it’s cut. Pull the floss tight against the scissor edge, and it parts instantly. You can saw the scissor through the material WITHOUT closing the blades, so you have a new type of cutting device that offers a different style of cut than scissors.
Typically most scissor cuts (with precision scissors) are done up and away from the shank. Both right-handed or left-handed tiers will have the scissor in front of the fly, cutting back toward the tail with scissor points elevated above the shank. This induces a tapered angle to the cut which is thin closest to the shank and wider as the cut procedes down the material towards the tail. By touching or sawing with the blade you can cut from either direction, tail to head or head to tail, which gives a bit different profile on the severed material butt.
If you decide the cut needs to come from a different direction than traditional, make sure you attach the material with this new directional force in mind. Cut or saw with the scissor edge in the same direction you wrapped the material as pulling or tensioning the item in the opposite direction will loosen it. Tinker with this to understand the options you have.
As with surgery scissors, especially those with Tungsten Carbide inserts, avoid cutting down towards the finished areas of the fly. At least minimize these cuts where possible. The scissor is so sharp that hitting the completed ribbed body, when cutting a material on a future step, could cut through the wire rib, fur, and sever six or eight turns of thread, ensuring your fly comes apart instantly. Cleaning the hook shank of the remnants of a poorly tied effort is possible with a simple sawing motion to remove all the mats off the bare hook.
… and yes, I’m still commiting most of this to my muscle memory, but so far … still have all nine digits intact.
How to Purchase Mizutani Scissors
My understanding is the wait time on these scissors is non-trivial. I have heard mention of “months” of wait for a completed pair, so you need to plan accordingly. The scissor is available from the Dolly Varden Fly Shop in Hokkaido, Japan, and from their website you can add yourself to the notification list and be informed when new stock arrives. Their email address is dolly@dorllyvarden.com, and they offer worldwide shipping.
In Summary:
These are an outstanding general purpose scissor for the professional tyer, not for the occasional hobbyist. Their 4.25″ length is traditional for a small pair of scissors, and they currently offer only the single size in four different alloy/finishes for fly tiers.
The fact that I like this scissor does not mean you will like it, as I have tied both commercially, professionally, and occasionally – and have spent many hours (and many dollars) using precision scissors. The Mizutani scissor is a wonderful instrument that likely will become your workhorse scissor, but is not appropriate for everyone due to their sharpness and potential to cause injury. It would likely make a great gift for someone that ties lots of flies and has been doing so for many years, but this tool is not for the beginning fly tier.
