The KIKU® Jinshari™ Knife
The KIKU® Jinshari Knife is the first of it's kind.  One of the first members of the KIKU® Elite series, this knife was specifically designed to work on bonsai and perform tasks unique to bonsai.  The Jinshari was created to fill the need for a specialized jin and shari tool.  The name Jinshari is derived from the knife's primary use which is creating shari's and jin's on bonsai.  You will quickly find that the Jinshari™ is an integral part of your tool roll or bag.

Each material was carefully chosen and tested to meet the demand of enthusiastic bonsai practitioners.  

DC53 Japanese Stainless Steel Construction - This tool is constructed from  1/8" Japanese DC53 tool steel.  The tool was vacuum heat treated to a hardness of 61-63 HRC.  DC53 steel is well regarded for it's wear resistance and durability while still providing a ultra-sharp edge.

Multiple Cutting Edges - The Jinshari' features a very sharp tip with small 1/2" straight blade, a 1 1/8" concave edge and a 3/4" convex edge.  The combination of edges makes the Jinshari™ a versatile tool for all deadwood cleaning, jin, shari and most other bonsai deadwood work.

Carbonized Acacia Wood Handle -  
The carbonized acacia wood handle's density is 62 pounds per cubic foot.  This places the handle's wood between oak (45 lbs/cubic foot) and marble (80lbs/cubic foot) so it is very, very hard.  The dark wood also has great visual appeal.

Hidden 3/4 Tang
 - The hidden tang fills nearly the entire handle making it structurally sound for even the most demanding uses.  The tang has a series of unique rectangle notches that were precision cut to assist the epoxy in preventing the tang from slipping the handle. The tang and handle are secured with a pure copper ferrule.  

The Jinshari™ is extremely sharp and care should be taken when handling or using the knife.  Keep this and all knives away from children and pets.  This is not a toy and should be stored in a safe location.

Just based on looks

I have not used it but based on looks and the way it came on it’s own dedicated box plus how sharp it is I give this 5 stars. Can wait to use it

Great Tool. But They Wouldn't Ship To Canada

I love the tool, however they won't ship to Canada anymore. I had to have the tool delivered to a relative in the US, and then have them mail it to me in Canada. Superfly used to ship directly to me, but not anymore. So I only buy special items, like the Jinshari, from them now.
