Our JCK Original Fu-Rin-Ka-Zan brand of Japanese traditional-style knives are hand forged and hand sharpened by top-ranking forge-smiths, sharpeners and craftsmen in Sakai City, Osaka.

They take exceptional care to ensure that every single detail of their knives is correct, from the initial forging to the final sharpening, the fit and finish of these knives is outstanding.

This is the special order made Fu-Rin-Ka-Zan Limited Model, Hon Kasumi Blue Steel No.1 Usuba Knife and available with limited quantity.  Beautiful Masterpiece of Mirror Polished Blue Steel No.1 Usuba Knife comes with Octagon Shaped Ebony Wood Handle and hand crafted Magnolia Wooden Handle.

A cutting edge of high carbon Hitachi Blue Steel No.1 that is welded forged with soft iron for increased toughness and ease of re-sharpening. Blue Steel No.1 makes extra high cutting performance, edge retention and hardness. 

The Usuba is ideal for cutting vegetables and fruits which are served raw, because the thin and sharp blade produces cut surfaces with very little cell damage, and this minimizes the discoloration and change in flavor often caused by oxidation. The versatile middle section of the blade can be used for thinly slicing vegetables and also for performing the specialized Katsuramuki ("Rotary peeling”) technique.

 Japanese Traditional Style “Wa-Bocho” knives generally come with Single bevel edge for right handed use (the opposite side of blade is ground flat with slightly concaved shape). The reverse grinding left handed version is also available at 50% extra of regular price. (Sorry for much extra! Due to a small demand for the left handed version in Japan, it is costly to run a special small production from the beginning step). We try to keep the left handed versions in stock, but once sold out, it may take 60 to 90 days for delivery. Please contact us first for the availability at email.

We believe the quality and cutting performance of Japanese knives are the best in the world, and hope you enjoy fine craftsmanship and sharp edge with your new knife. With proper cares, every Japanese knife should be your special cooking partner for long times.

Important

This is the Carbon steel blade kitchen knife that can get rust and discolor easily, and requires extra care and attention to prevent rust. 

• Please do not put the knife in the dishwasher machine for cleaning.
• Please do not leave the knife in water or wet condition for long time.
• After using, please hand wash the blade, bolster and handle thoroughly, and wipe it clean and dry with soft clothes. Please apply Tsubaki oil on the blade and keep it in dry place.
• This is an extremely sharp knife. Please use special cares in using and storing it.
• Unlike German made knives, Japanese knife blades are ground to thin cutting edge for sharper cutting and easier re-sharpening. Please protect the edge from hitting hard materials to avoid chipping or cracking.

• We recommend using Japanese whetstones to re-sharpen the knife, when it gets dull.
