─── Core Steel ▪️ Blue #1 Steel ───
▸ Belongs to the Yasuki Steel series by Hitachi Metals, with chromium and tungsten added to a white steel base to enhance performance.
▸ Can reach approx. HRC 62–64 after heat treatment, providing exceptionally outstanding cutting edge sharpness.
▸ Owing to its high carbon content and alloying elements, it features supreme sharpness and edge retention, making it ideal for delicate slicing.
▸ Being a high-carbon steel, it is prone to rust, and its high hardness results in increased brittleness, requiring higher care in use and maintenance.
─── Craftsman's Soul ▪️ Mizuno Tanrenjo ───
▸ Mizuno Tanrenjo was founded in Sakai City in 1872 by the first-generation smith, Torakichi Mizuno, establishing the "Minamoto Akitada" brand to forge both samurai swords and culinary knives.
▸ The 2nd-generation master Masanori Mizuno forged four talismanic evil-warding sickles using antique nails from Horyu-ji Temple, which were enshrined atop the temple's five-story pagoda for spiritual protection.
▸ The 3rd-generation master Sadaaki Mizuno studied under Living National Treasure Sadakazu Gassan; his exhibited Honyaki Yanagiba contributed directly to Sakai Uchihamono being officially designated as a Traditional Craft of Japan by the Japanese government.
▸ The 4th-generation master Yasuyuki Mizuno was granted an audience by Prince Takahito of Mikasa and awarded the prestigious honor of "Tairan," bearing the engraved inscription "賜台覧" (Bestowed with Imperial Inspection) on the blade spine.
▸ The 5th-generation master Jun Mizuno is globally renowned for his signature "Kawazu Choji" (tadpole-clove) hamon temper lines, highly acclaimed and sought after by professional chefs both in Japan and overseas.
─── Knife Type Introduction ▪️ Unagi Saki (Edo-style) ───
▸ Edo-saki is a single-bevel knife specialized in preparing eel in the Kanto region, designed specifically for the "back-opening" method to avoid the taboo of slitting the belly (seppuku).
▸ The blade tip features a sharp triangular angled edge that can precisely pierce the slippery and tough skin of the eel's back to initiate the cut.
▸ The blade thickness reaches 4 to 6 mm with a forward-balanced center of gravity, allowing eel bones to be cut effortlessly using the blade's own weight.
▸ Most blade lengths range from 150 to 240 mm; its short blade and wide profile geometry allow artisans to cut with extreme precision along the spine.

☆【 Care Instructions 】
Carbon steel oxidizes easily. After the surface is thoroughly dried, be sure to apply a thin, even coat of food-grade knife oil (such as camellia oil or white mineral oil) to the blade to lock out moisture and prevent rust.
☆【 Professional After-Sales Maintenance 】
In-store professional kitchen knife sharpening services are available to keep your prized knife performing at its peak.
⚠️ Avoid Extremely Hard Objects ⚠️
Never chop frozen food or hard bones to prevent blade damage, chipping, or breakage.
⚠️ No Dishwasher or Dryer ⚠️
Do not clean in a dishwasher or dish dryer; high heat and harsh detergents will damage both the blade and the handle material.
⚠️ Standard Cleaning Procedure ⚠️
Hand wash with warm water after use, dry thoroughly and immediately with a dry cloth or soft towel, and store in a well-ventilated, dry place.
❁【 Return and Exchange Standards for Aesthetic Manufacturing Marks 】
All high-end kitchen knives sold in our store are authentic and genuine from the manufacturer. Because the handcrafted production process includes manual grinding, hand sharpening, and saya fitting adjustments, slight micro-scratches on the blade surface are "normal factory conditions" rather than quality defects. Every piece is strictly inspected before shipment. Perfectionists, please consider carefully before placing an order.
❁【 Kind Reminder 】
All product photos are taken from actual items. However, due to lighting, shooting angles, or different display monitor settings, slight color variations between the photos and the physical product may occur. Buyers who are extremely sensitive to color differences should consider carefully before ordering. The color of the actual received item shall prevail.
