Experienced Forge-Smith Takeshi Saji creates a variety of fine masterpieces and custom knives, and is always seeking new possibilities that will make each of his knives unique and outstanding.
Since the year 2020, we have been working closely with Master Saji to create a new range of top-tier knives — including unique one-of-a-kind pieces and limited edition custom knives that often feature exceptional handles. Today, we are very excited to introduce the Saji SUMMIT ― Limited Edition Custom Series.
This time, Master Saji has chosen to work with SRS-13, a high-quality Powdered High Speed Tool Steel produced by Sanyo Steel Company. Master Saji has great confidence in the supreme cutting performance, edge retention, and corrosion resistance offered by SRS-13, because it has a fine microstructure and a very rich chemical composition — including a high percentage of Carbon, similar to that of Japan's premium Aogami Super Hagane (blade steel).
The blade features a three-layer clad construction (San-Mai) with a hard SRS-13 core sandwiched between two layers of softer stainless steel cladding. The surface showcases Master Saji's unique 網細工 "MESH" design Tsuchime (hammer-forged) texture — a striking, hammered texture , handcrafted finish unlike any of other knives. The attractive shiny SRS-13 blade core contrasts strongly against the textured, soft stainless steel outer cladding layers, making each knife a true work of art.
One day at the US Knife Show, we accidentaly met with this rare and stylish, "JUMA" Light Green Color Material. JUMA is a high grade, modern raw material for handcrafted works of art. JUMA is a resin based material has great durability and makes very beautiful & attractive appearance (like the Dragon's Scale) We promptly requested Master Saji to use this special material for his very limited edition knife and now another masterpiece of Saji SUMMIT- Limited Edition Custom Series knife is available.
The Unique Custom Handmade JUMA "Light Green Color" Custom Handle has a beautiful appearance and to ensure that it can be gripped comfortably, it has been carefully contoured and polished by hand. A decorative Mosaic Pin secures the handles scales and a stainless steel bolster has been fitted to improve the durability and blade balance of the knife.
A mainstay of professional Western kitchens, the Petty knife is a small general-purpose knife used for peeling, shaping, and slicing fruits and vegetables, chopping herbs, and making garnishes. The compact size and relatively narrow blade make it very nimble and precise — ideal for detailed, controlled cuts.
What is SRS-13?
SRS-13 is a Powdered High Speed Tool Steel produced by Sanyo Steel Company. It has a fine microstructure and a very rich chemical composition — including a high percentage of Carbon, comparable to Japan's premium Aogami Super Hagane. This results in supreme cutting performance, outstanding edge retention, and excellent corrosion resistance. SRS-13 is a favored choice among top-tier Japanese custom knife makers who demand the very best in performance and longevity.
How is Takeshi Saji able to make such great custom handmade handles?
Takeshi Saji has produced a wide variety of knives during his long career, including a large collection of Custom Hammer Forged Traditional Outdoor Knives. Just as he has spent many years perfecting his hammer forging techniques, he has also invested significant time and energy in perfecting his techniques for handcrafting custom knife handles. This experience and knowledge has made Takeshi Saji and his knives particularly distinctive and noteworthy among Japanese knife makers. His own path, ideas, and spirit have created the current Takeshi Saji Custom Kitchen Knife Collection.

This knife comes with 50/50 double bevel edge geometry for both right and left handed use.
For your information, Japanese Kitchen knives are generally designed for right hand use with a slightly thicker and rounded grinding on the right side blade and a less rounded (almost straight flat) grinding on the left side blade. However, both right and left handers can use knives with double bevel edge sharpened 50/50 without problems.
We believe the quality and cutting performance of Japanese knives are the best in the world, and hope you enjoy fine craftsmanship and a sharp edge with your new knife. With proper care, every Japanese knife should be your special cooking partner for a long time.
