Description
CR1070: Koji Hara Ichi
Columbia River

These knives have been designed to give you a choice between conventional opening or super-fast assisted opening, employing our patented OptiFast assisted opening mechanism. We call it OptiFast because the assisted opening mechanism is both optional, and also optimum in terms of simplicity and reliability. You initiate opening using the thumb stud or disk, and after 30°, OptiFast takes over, giving instant lockup. The OptiFast spring is held in place by a single set screw which allows you to remove or replace the spring in minutes. It gives a new level of choice in folding knives. The cutaway view below shows the OptiFast mechanism in place.

Award-winning Japanese knifemaker Koji Hara created this perfectly-balanced personal knife series especially for CRKT.

We were delighted when internationally-known Japanese knifemaker and American Knifemakers’ Guild member Koji Hara agreed to design a personal knife for CRKT. Koji is noted for his custom folders in exotic materials, and is especially known for his carving of the handle material into a classic terraced landscape that he calls his “Air-Step” design. Our goal was to apply Koji’s remarkable design sense to a small personal folder which could incorporate our patented OptiFast assisted opening mechanism.

Logically, we called this first CRKT Koji Hara series Ichi, Japanese for “one.”

For rigidity and strength, we used our InterFrame open build, with two 420J2 stainless steel liners. In a first for CRKT, we created layered injection molded scales of Kraton and Zytel, the latter with Koji’s terraced Air-Step design. The result is a small knife that gives good grip, fits the hand nicely, and is truly functional for a variety of work tasks.

The handle tapers neatly into a modified drop point pen blade with a high hollow grind made of high carbon stainless steel. An ambidextrous thumb disk allows easy one-hand opening.

Most of us can’t carry a Koji Hara custom collectible daily, but the Ichi is a friendly and affordable reminder of one of Japan’s premier custom knifemakers.

Pros: Handle Material, Lock Type, Lock Ease of Use, Overall Quality
Cons: None
Great buy for this price
I had ordered this knifle because of Tge blade lenght, so that I can carry ut on a flight, then to find out tgst Tge TSA has reclined the rule on any knifle can not be brought onto an airplane, so I have a short blade knifle as an eveEDC knifle.I read some of the review as to how disappointed some people were with thus knifle.I like Tge construction of it and Tge matrrials used! the blade is super sharp,but the only issue I had with it was the opening of the blade, the assisted oper needs to get use to it but one you do it works very well and fast!I have a Kershaw Voit which is a more aggressive blade then the Ichi,I love both of Tgese knives!

The thumb stem will break you thumb nail in trying to open the knife
The blade was very sharp, but the problem is in trying to open the blade, the thumb stem is too short and you will break you thumb nail in trying to opening the blade!mr Koji ?Hara, needs to change how the opening method on his knife,I thought the size of the blade is great to get pass FSA at the airports,I believe that a 21/2" blade is allowed ona plane, but the "Ichi is not an EDC knife for me,I also ordered the Kershaw Voit II and that is a great ?EDC knife with an Attutude! Great filpper and great blade!On the KershawI would give it a five stars!
